Hydrogen, helium, lithium, beryllium and boron, carbon, nitrogen, oxygen, neon, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon, potassium, calcium, scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper and zinc, gallium, germanium, selenium and bromine.

I am hydrogen, I am the lightest, rockets rely on me to transport satellites, I am helium, I am a rogue, and I have the worst electron loss. I'm lithium, with low density, and it bubbles when it meets water and acid. I'm 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, which is a flame retardant and can be hydrogenated to synthesize ammonia. I am oxygen. Forget it. I'll panic when I leave.

Matters needing attention in the periodic table of chemical elements in senior high school

The nonmetallic elements of IVA are the main force to form atomic crystals, which can not only form simple atomic crystals: diamond and silicon crystals; Atomic crystals of compounds can also be formed: silicon dioxide (crystal, when applicable) and silicon carbide (emery).

The highest valence of all main group elements is equal to the outermost electron number of the element atom (that is, the main group ordinal number where the element is located). The outermost element with only 1 electron must be IA.
