WebThe atomic number of lithium is 3. That is, the number of electrons in lithium is 3. Therefore, a lithium atom will have two electrons in the first shell and one in the 2nd shell. Therefore, the order of the number of electrons in each shell of the lithium(Li) atom is 2, 1. Electrons can be arranged correctly through orbits from elements 1 to 18. Lead's per-particle abundance in the Solar System is 0.121 ppb (parts per billion). This figure is two and a half times higher than that of platinum, eight times more than mercury, and seventeen times more than gold. The amount of lead in the universe is slowly increasing as most heavier atoms (all of which are unstable) gradually decay to lead.
