Question

An element ,'X' belongs to third period of p-block.It has four electrons in the outermost shell.Deduce the atomic number of element 'X'.

Answer 1

Element X is Germanium in period number 3 of p-block.

Answer 2

Explanation:

The element belongs to 3rd period. i.e has 3 orbitals, as it belongs to p block and has 4 electrons in p shell, thus the electronic config will be 1s2 2s2 2p6 3s2 3p4 and atomic no. will be 16 and hence element Sulphur.
