Question

which group of the periodic table is the following element found in? ne3s^2 3p^2

Explanation:

Step1: Determine the valence - electron configuration

The electron - configuration is given as $[Ne]3s^{2}3p^{2}$. The valence - electron configuration is $3s^{2}3p^{2}$, which means there are 4 valence electrons.

Step2: Relate valence electrons to group number

In the periodic table, for main - group elements (groups 1, 2, and 13 - 18), the number of valence electrons is equal to the group number (with groups 13 having 3 valence electrons, 14 having 4 valence electrons, etc.). Since there are 4 valence electrons, the element is in group 14.

Answer:

Group 14
