What is the formula for reciting the first 20 elements in the periodic table of chemical elements?

Periodic table memory formula: periodic memory

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-marrying Kangtai is counter-revolutionary.

It is best to remember five of the first 20 elements, and you will be familiar with them if you read more.

Element property formula

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.

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;
