• electronic configuration of nitrogen is 2,5
• electron configuration of phosphorus is 2,8,5

$\huge\purple{\boxed{\red{\mathbb{\overbrace{\underbrace{\fcolorbox{blue}{white}{\underline{\purple{Answer : -}}}}}}}}}$

there are four valence electrons present in outermost shell of silicon

Answer 2

Explanation:

N=1S2 2S2 2P3

P=1S2 2S2 2P6 3S2 3P3

4 valence electron are there in the outermost shell of the silicon
