Question

Element X has a ground-state valence electron configuration of $n{s}^{2}n{p}^5$.
Select the formula of the carbon compound most likely to be formed.

• A. $CX$
• B. $C{X}_2$
• C. $C{X}_4$
• D. $C{X}_6$

Answer 1

The correct option is C $C{X}_4$

Element X has a ground-state valence electron configuration of $n{s}^{2}n{p}^5$. It will share one electron to complete its octet. Thus, it will form one covalent bond. C atom shares 4 electrons to complete its octet. Hence, C atom forms 4 covalent bonds. Thus, one C atom will combine with 4 X atoms. aThe formula of the carbon compound most likely to be formed is $C{X}_4$.
