The first cycle: hydrogen and helium violation.

The second cycle: lithium, beryllium, boron, carbon, nitrogen, oxygen, neon-carp skin holds carbon, eggs feed milk. The third cycle: Na, Mg, Al, Si, P, S, Cl, Ar-that beauty Guilin has a green tooth (a little scary).

The fourth cycle: potassium, calcium, scandium, titanium, vanadium, chromium, manganese-marrying Kangtai is counter-revolutionary, iron, cobalt, nickel, copper, zinc, gallium and germanium-iron ancient newlyweds, arsenic, selenium, bromine and krypton-angry shock. The fifth cycle: Rb, Sr, Y, Zr, Nb-so I tell you, Mo, Te, Ru-great, Rh, Pd, Ag, Cd, In, Sn, Sb-Laobayin Xi Di, Te, I, Xe-a little salty.

SClArKCa (sulfur, chlorine, argon, potassium and calcium), ScTiVCrMn (scandium, titanium, vanadium, chromium and manganese) and FeCoNiCuZn (iron, cobalt, nickel, copper and zinc).
