Question

Which metalloid, with four valence electrons in the fourth energy level's p subshell, typically does not form ions?

a) Silicon
b) Phosphorus
c) Sulfur
d) Chlorine

Answer 1

Silicon is the metalloid with four valence electrons in the fourth energy level's p subshell and it usually forms stable covalent bonds rather than ions. The correct option is (a).

Step-by-step explanation:

The metalloid with four valence electrons in the fourth energy level's p subshell that typically does not form ions is silicon (Si).

Silicon has the electron configuration 3s²3p², meaning it has four valence electrons in the third shell, which is its outer shell. Silicon is known for forming covalent bonds rather than ionic bonds, often creating tetrahedral structures where it is sp³ hybridized.

Unlike some other elements, silicon does not typically form ions due to the stable tetrahedral structures it forms and the relative strength of its covalent bonds.
