The element with atomic number 32 belongs to which period of the periodic table?

1. Second
2. Third
3. Fourth
4. Fifth

Correct answer: Fourth

Solution

Period 1: Z = 1-2 (2 elements). Period 2: Z = 3-10 (8 elements). Period 3: Z = 11-18 (8 elements). Period 4: Z = 19-36 (18 elements). Z = 32 falls in Period 4. (Germanium, Ge, 4th period, Group 14.)
