How to remember the periodic table of elements

Question 1: How can the first 20 elements of the periodic table quickly remember nitrogen N 14? Remember: eggs will die if they fall off the bridge!

Analysis: The egg (homonym of nitrogen) fell off the bridge (lowercase n refers to an arch bridge) and died (homonym of 14)!

In this way, you can remember the name, symbol and original quantity together.

If necessary, you can go to my Baidu data to find a connection method, or use memory to connect.

Question 2: Memory skills of the periodic table of elements. I am hydrogen, I am the lightest, and rockets rely on me to transport satellites. I am helium, I am a rogue, and I have the worst gain and loss of electrons; I am lithium, with low density, which bubbles when it meets water and acid; I am beryllium, cheating, although metal is difficult to ionize; I am boron, with poor electronics, which is very different from my home; I am carbon, slow to react, and can form a chain into a ring; I am nitrogen, I am a flame retardant, and hydrogenation can synthesize ammonia; I am oxygen, don't think about it, I will be flustered when I leave; I am fluorine, the most vicious, and it is enough to catch an electron; I am neon, not bad. When I was electrified, the red light was released. I am sodium, with a big temper, and I get angry when I meet acid and water; I am magnesium, I love beauty most, and my photography and fireworks are brilliant; I'm Al. I bathe in concentrated sulfuric acid at room temperature. I am silicon, black ash, and information components pile me up; I am phosphorus, a pest, and my name is on the poison list; I am sulfur, and I have been good at precipitating metals for a long time.

Question 3: How to quickly remember the periodic table of elements? The specific method of homophonic memory element periodic table is as follows:

First, remember by cycle.

The first cycle: "hydrogen helium". Homonym: "Hey!" It tells us a good news-it is not difficult or easy to recite the periodic table of elements.

The second cycle: "lithium beryllium boron carbon, nitrogen oxyfluoride neon." Homonym: "raccoon skin holds charcoal, eggs raise milk." It means that foxes are used to hunt hides and coal, and those hatched from eggs do not eat milk.

The third cycle: "sodium magnesium aluminum silicon, phosphorus sulfur chlorine argon." Homonym: "Latin American tourists, stay in the forest!" It means that when a person comes back from a trip to Latin America, he can't help but sigh: "There is another village!" "

The fourth cycle: "Potassium, calcium, scandium, titanium, vanadium and chromium are fierce, while iron, cobalt, nickel, copper, zinc and gallium exist, while arsenic, selenium and bromine are krypton." Homonym: "Jia Gai's troubles against the bag fell sharply, the iron hoop cracked the barrel, and his body washed the smelly shell." It means: a man named Jia Gai, who was tired and upset with his bag on his back, threw it on the ground (violently); The barrel with broken iron ring belongs to a new family; Moving makes you dirty all over, so you must take a bath and get rid of your smelly shell.

The fifth cycle: "rubidium strontium yttrium zirconium niobium molybdenum technetium, ruthenium rhodium palladium silver cadmium indium tin, antimony tellurium iodine xenon." Homonym: "If you think you have told me your purpose, ruthenium handcuffs will insulate people, and you will cry in three places." It means: if you are asked to think about a question, the answer is told to you without a purpose (in some dialects, "you" has no meaning). A few years ago (during the ten-year turmoil), intellectuals were persecuted. They handcuffed people with ruthenium handcuffs and cut them off from the outside world. He cried sadly, and his tears fell to the ground at three o'clock.

The sixth cycle: "Cesium, barium, lanthanum, hafnium, tantalum, tungsten, rhenium, osmium, iridium, platinum, mercury, thallium and lead, bismuth, plutonium and radon", homophonic: "Don't come if the river is blocked, and Russia will give him money according to platinum." It means: stop the river with a quilt. This kind of stupid thing is "don't come" (don't do it). Russia sells a lot of platinum in the international market every year, and his money depends on platinum. If this continues, it will definitely go bankrupt, and those in power in Russia will be opposed by the domestic people and will be "bombed".

There are 15 lanthanides in the first cycle: "La, Ce, Nd, Sm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb, Lutetium." Homonym: "There are many ordinary women in Heather, but Zat has lost the ears of the enemy." There is an ordinary woman with a lot of money in the South Market. There is a guy named Zat playing with fire and fighting (enemy fire). His ear was burned and he lost one.

The seventh cycle: "francium radium actinide." Its homonym is a warning to us: "Lightning protection!"

This cycle contains 15 actinides: "actinium thorium praseodymium uranium plutonium americium, actinium thulium thulium thulium thulium thulium thulium thulium." Homonym: "Artoo spilled oil and wiped it with a cloth, and opened a waste door and locked it." It means: Artu threw himself on the oil and stained his clothes, and wiped them with a cloth; Why did the door lock (shovel) open? Because it is unsafe to break the door (abandoned door) (some dialects say it is unsafe).

Second, according to family memory

Group IA: "lithium, sodium, potassium, rubidium, cesium and francium." Homonym: "clear armor as a precaution." It means: in the face of a strong enemy, pack your things and pick up your armor, just like building a city.

Group IIA: "Beryllium magnesium calcium strontium barium radium." Homonym: "Pimeigai is a shellfish." It means: animals with beautiful hard shells (called "lids" in northern dialect) are shellfish.

Group ⅲ a: "boron, aluminum, gallium, indium, thallium." Homonym: "Friends marry because of him." It means: so, marry him, because he is a friend and can be a partner.

Group ⅳA: "C, Si, Ge, Sn, Pb". Homonym: "People who explore your wealth will move west." Because there are many treasures in the southwest, people who explore precious minerals will go to the west.

VA family: "nitrogen, phosphorus, arsenic, antimony, bismuth." Homonym: "light scales, shave." It means: there are only a few scales on the fish, because the fish has been scraped.

ⅵ A group: "oxygen, sulfur, selenium, tellurium, polonium." Homonym: "sheep flow to the west slope." Sheep are flowing on the western slope.

ⅶ A home: "Fuwan iodine." Homonym: "Buddha, smell some moxa." Superstitious people have no money to buy incense, so they have to smell the smoke of wormwood on their way to worship Buddha.

Group o: "helium-neon-argon-krypton-xenon-radon." Homonym: "Cough! Milk is like Shandong! " It means: cough! A milk baby conquered Shandong!

Family IB: "copper, silver and gold." Group Ⅱ B: "Zinc, cadmium and mercury." Group ⅲ b: "scandium yttrium lanthanum actinide." Homonym: "Today, the same person, the heart is away from the point, and the kang is rotten." It means that people who are together are still not United (heart diaphragm). No one maintained it, and as a result, the kang that everyone slept in (the northerners slept on the fire kang) was broken.

Group ⅳB: "titanium, zirconium and hafnium." ⅴ B family: "Vanadium and niobium ... >>"

Question 4: There is no trick to memorizing the periodic table of elements. What I can offer here is the back of the five elements. I can make a plan, five a day, and remember the names and symbols of the elements. After that, you can draw the periodic table of elements and check which elements can't be remembered by filling in the elements. Some seniors write the periodic table silently once a week. Later, they can silently draw the frame of the periodic table upside down, and you can know which element it is by pointing to which frame. Both slow back and solid back can achieve good results.

The periodic table of elements is the cornerstone of learning chemistry. If you can't recite the periodic table, you can't learn chemistry.

Question 5: Reciting skills of the periodic table of elements. The first cycle: hydrogen and helium invasion.

The second cycle: lithium, beryllium, boron, carbon, nitrogen, oxygen and neon-carp skin holding carbon eggs to nourish fu milk.

The third cycle: Na, Mg, Al, Si, P, S, Cl, Ar-that beauty Guilin has green teeth (that beauty ghost shows green teeth).

The fourth cycle: potassium, calcium, scandium, titanium, vanadium, chromium, manganese-marry Kangtai counter-revolution

Iron, cobalt, nickel, copper, zinc, gallium and germanium-newlyweds with iron-are miserable.

Arsenic, Selenium, Bromine and Krypton-Anger Shock

The fifth cycle: rubidium, strontium, yttrium, zirconium and niobium-so tell you.

Molybdenum, technetium and ruthenium-amazing.

Rhodium, Palladium, Silver, Cadmium, Indium, Tin and Antimony-Old Ba Yin Ge Yin Xidi

Xenon-iodine telluride positioning wizard

The sixth cycle: cesium, barium, lanthanum, hafnium-(color) shell blue (color) river

Tantalum, Tungsten, Rhenium, Osmium —— But (see) Wu (crow) (lead) Lai goose

Iridium, platinum, gold, mercury and lead-a white towel.

Bismuth, polonium and radon-Never love winter (daytime)

The seventh cycle: rubidium, radium, actinium-very simple ~ that is-lightning protection!
