Phosphorus vs. Silicon: Comparing Outer Electrons - Chemistry Explained

Phosphorus has more outer electrons than silicon.

Here's why:

* Phosphorus (P) is in Group 15 (or VA) of the periodic table, meaning it has 5 valence electrons (outer electrons).

* Silicon (Si) is in Group 14 (or IVA), meaning it has 4 valence electrons.

Therefore, phosphorus has one more outer electron than silicon.
