Question

The element Q in group 16 has 3 shells if so
1. Write the period number of the element

Answer 1

Answer:

The atom of the element has three shells. So, the period number is 3. The atom of the element has six valence electrons. So, the group number of the element will be 16 (6+ 10).

Explanation:

Answer 2

Answer:

3

Explanation:

The period of an element corresponds to the principal quantum number of the Valence shell.

Since there are 3 shells, the principle quantum number of the valence shell (i.e. the outermost shell) ought to be 3, implying, element Q belongs to 3rd period.
