Chemical element symbol mnemonic method

How to make students remember nearly 30 element symbols as soon as possible? In addition to rote learning, I also searched some ways to teach you. I hope you find memory interesting and remember it quickly.

Fast memory method of chemical element symbols

First, the pinyin method

Sodium (Na), Barium (Ba), Fluorine (F), Tungsten (W) and Lithium (Li): The Chinese pinyin of these element names is similar to the element symbols of this element, such as sodium (Na). Sodium? Is the Chinese pinyin n? ; Barium (Ba)? Pronunciation with Chinese phonetic barium? b？ Pronunciation and English letters? Answer? Pronunciation and spelling; Fluorine (f)? Fluorine? What is the first letter of the pronunciation? f？ , tungsten (w),? Tungsten? What is the first letter of Chinese Pinyin? W? ; Lithium (Li)? Lithium? What is the use of Chinese Pinyin? lǐ？ .

Second, the image method

The element symbols of some elements can be vividly remembered. For example, that tungsten element (W) can be combine with tungsten wires in incandescent lamp. W? Form; Sulfur may be combined with running water in winding streams. What is its shape? s？ Shape; Oxygen element (O) can be associated with the circle of the sun; Potassium (K) can be related to the shape of open scissors when cutting nails.

Third, homophonic method

For example, the element of gold (Au) can be imagined: someone suddenly sees a shiny piece of gold on the ground, and he can't help but send it out? Ouch? This sigh, this? Ouch? The pronunciation of English letters isn't it? Au？ Pronunciation of?

Fourth, rhyming grammar

One: letter contrast memory method.

Such as: gold, silver, aluminum and argon? Answer? At the beginning? b？ Ba, Br, Ca, Cu, C and Cl at the beginning of the word? c？ ,? m？ Lead, manganese and magnesium.

Compare and memorize common element symbols in English alphabetical order;

A: Silver (silver), aluminum (aluminum), argon (argon) and gold (gold).

B: Be (beryllium), B (boron) and Ba (barium).

C: C (carbon), Cl (chlorine), Ca (calcium), Cu (copper).

Fluorine: fluorine

H: H (hydrogen), He (helium), Hg (mercury).

I: I (iodine)

K: K (potassium).

M: mg (magnesium), Mn (manganese).

N: n (nitrogen), Na (sodium), Ne (neon).

oxygen

P: P (phosphorus), Pb (lead).

S: S (sulfur), Si (silicon).

Tungsten: tungsten

Z: Zn (zinc).

Second, the first twenty elements are recited in groups of five.

Hydrogen (H) Helium (He) Lithium (Li) Beryllium (Be) Boron (B),

Carbon (c) nitrogen (n) oxygen (o) fluoriNe (f) neon (ne),

Sodium (Na), magnesium (Mg), aluminum (Al), silicon (Si) and phosphorus (P),

Sulfur (S) chlorine (Cl) argon (Ar) potassium (K) calcium (Ca).

Third: metal activity sequence table (also convenient for future application).

Potassium (k), calcium (ca), sodium (Na), magnesium (Mg), aluminum (al),

Zinc (Zn), iron (Fe), tin (Sn), lead (Pb), hydrogen (H),

Copper (Cu), mercury (Hg), silver (Ag), platinum (Pt) and gold (Au).

Five, associative memory method.

Carbon symbol: c English word coke is a carbonated drink, so carbon-c

Symbol of copper: if there is a lot of copper in Cu's body, it is harmful to human body, so we have to say: Goodbye. Homophonic Cu

Symbol of silicon element: silicon turtles live long, so they don't die? Die? Reading? Is it?

Symbol of oxygen: O people must breathe oxygen to survive. o？ It's like breathing with your mouth open.

Sulfur symbol: the homonym of S sulfur? Flow? S is like running water.

Helium symbol: He-Ne symbol: Ne pinyin? Sea? Nye?

Nitrogen symbol: n Nitrogen is considered as a useless gas? No? English? No? So nitrogen is? n？

Symbol of hydrogen: H hydrogen has low density and light weight, and is often made as a symbol of the rising of hydrogen balloons? h？ It is like a ladder for you to climb up.

Calcium symbol: Ca Association? Ca？ Canned calcium

The symbols of potassium: k, a, b, c, d and a rank first among kings, so? k？

Manganese symbol: Meng Nan.

Magnesium symbol: Mg beautiful girl Meigirl

Symbol of copper element: Cu copper rusts and turns blue-green, feeling sour, like vinegar (Cu).

Symbol of aluminum: Excessive aluminum is harmful to human body and may lead to Alzheimer's disease. Is Al very old?

Symbol of phosphorus: P phosphate? p？

Ba element symbol: Baba is a treasure? Baby?

Symbol of zinc: zinc is good for brain development, so zinc supplementation is? Long brain? Zhangnao? Namely. Zn？

Symbol of silver element: Ag? Angel.

Mercury symbol: Hg drinking water silver? He gong?

Six, decentralized memory method

For the symbols of common elements given in textbooks, if you concentrate on one class, the memory density is too high, and it is difficult to remember them all. Combined with the infiltration of the previous content, if the memory is dispersed by the above methods according to their respective characteristics, the difficulty of memory can be greatly reduced.

You can also make your own element playing cards, write two or three element symbols on the front of the cards, and write the corresponding element names on the back. Recite a few words every day, ask each other questions and remember the game. I believe it will be remembered soon.

Of course, there are many ways to remember, and students will find a suitable way to remember. The memory of element symbols is a difficult point for students to learn chemical knowledge for the first time, and it is also the first distinguishing point. No matter what methods or means are adopted, the purpose is to master the commonly used element symbols. As long as you get through this, you're halfway there.
