Chemistry rhymes for junior high school students

Chemistry rhymes for junior high school students:

1 A simple formula for memorizing 20 chemical elements.

Hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon, sodium, magnesium, aluminum, silicon and phosphorus, sulfur, chlorine, argon, potassium and calcium.

Memory tips:

Dear Li Pi Peng, magnanimous Yangfu Lai. (Hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon) That beauty Guilin, the beef should be added with calcium. (Sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon, potassium and calcium)

2 Chemical Elements Storyboard Rhyme:

Hydrogen, lithium, sodium, potassium, rubidium, cesium and francium - please join Li Na for a private interview;

p>

Beryllium, magnesium, calcium, strontium, barium and radium—comparable to Bill Gates’ being fired;

Boron, aluminum, gallium, indium, thallium—it’s impossible to marry a girl;

Carbon, silicon, germanium and tin Lead - explorers moving westward;

Nitrogen, phosphorus, arsenic, antimony and bismuth - eggs close to the body;

Oxygen, sulfur, selenium and tellurium polonium - raising cattle;

p>

Fluorine, chlorine, bromine, iodine, astatine - father and daughter embroider some love;

Helium, neon, argon, krypton, xenon and radon - the harm is caused by the first move.

3 The first 20 elements of junior high school chemistry jingle:

I am hydrogen, I am the lightest, rockets rely on me to transport satellites;

I am helium, I am a rogue , I am the best at gaining and losing electrons;

I am lithium, with low density, and will bubble up when exposed to water and acid;

I am beryllium, a swindler, although it is a metal that is difficult to ionize;< /p>

I am boron, a bit red, and I am very poor when it comes to electrons;

I am carbon, which reacts slowly and can form chains and rings;

I am Nitrogen, I am flame retardant, and can be synthesized by adding hydrogen to ammonia;

I am oxygen, I don’t need to think about it, I will panic when I leave it;

I am fluorine, the most vicious, just grab an electron Satisfied;

I am neon, not bad at all, I emit red light when electrified;

I am sodium, with a strong temper, and become angry when encountering acid or water;

I am magnesium, I love beauty the most, and the fireworks in photography shine brightly;

I am aluminum, I bathe in concentrated sulfuric acid at room temperature;

I am silicon, black and gray in color, I am piled with information components;

I am phosphorus, a harmful spirit, and my name is on the poison list;

I am sulfur, with a long history, and the best at precipitating metals;

I am chlorine, yellow-green in color, and I steal the metal electrons;

I am argon, with poor activity, and I send out the neon purple light;

I am potassium, Add fire, superoxide takes charge;

I am calcium, body loves, bones and teeth are all there.

4 The main valence formulas of common elements:

Fluorine, chlorine, bromine, iodine, negative monovalent; positive monohydrogen, silver and potassium and sodium. Remember the negative two of oxygen first; the positive two is magnesium, calcium, barium and zinc.

Positive three is aluminum and positive four silicon; the price changes will be returned below. All metals are at regular prices; one, two, copper and two, three iron.

Manganese is 24 and 67; carbon 24 should be kept in mind. Non-metals have negative numbers and positive numbers; chlorine has one negative number and a positive number of 157.

Nitrogen and phosphorus are negative three and positive five; different phosphorus are three nitrogen and two four. Sulfur has negative two and positive four and six; you will get used to it as you remember it.
