It's hard to forget how to recite the periodic table of chemical elements.

The most difficult thing to remember in chemistry is the periodic table of elements. I think many students find it difficult to recite. So, what are the good ways to recite the periodic table of chemical elements? Come and have a look with me!

How to quickly remember the periodic table of chemical elements by cycle

The first cycle: hydrogen and helium invasion

The second cycle: lithium beryllium boron carbon nitrogen oxygen fluorine-carp skin holding carbon eggs to raise 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 —— Newly married people with bitter taste of iron.

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 Eight Yin Ge Silver Xi

Deuterium, Iodine and Xenon-Locating Genie

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, mercury, thallium and lead-a white towel for him to hold.

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

The seventh cycle: Rb, Ra, Rb-lightning protection!

According to the memory formula of elements in the periodic table of chemical elements in the main family memory

The first host family: lithium, sodium, potassium, rubidium, cesium, cesium-invited Li Na to join the private visit.

The second largest family: beryllium, magnesium, calcium, strontium, barium and radium-comparable to Gates' thunder.

The third clan: boron, aluminum, gallium, indium, thallium-touch a woman and marry him.

The fourth largest family: carbon, silicon, germanium, tin and lead-explorers moved westward.

The fifth main family: nitrogen, phosphorus, arsenic, antimony and bismuth-eggs cling to the body.

The sixth largest family: oxygen, sulfur, selenium, tellurium, polonium-cattle-Xihoof.

Seventh Family: Fuwan Iodine-Embroidering fathers and daughters.

Eighth main clan: He-Ne-Ar-Kr-Xenon-Radon-Harmnyak moves first.

Recitation formula of the first 20 elements in chemistry

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, a little red, and poor in electronics;

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.

I am chlorine, yellow-green, and I rob metal electrons;

I am argon, which has poor activity and emits neon purple light;

I am potassium, and when I add fire, superoxide will charge;

I am calcium, body love, bones and teeth;
