Base your answer to the following question on the electron configuration for the ground state of element X, given below.

1s²2s²2p⁶3s²3p⁴

How many valence electrons does element X have?

Expert Solution

Electrons present in the outermost shell are called valence electrons.

Here 3rd shell is the outermost shell.

In outermost shell, there are 6 electrons ( 2 in s orbital and 4 in p orbital ).

So, element X has 6 valence electrons.
