Can someone help with this please? My teacher isnt responding to any of mine or my classmates requests for help

"Carbon dioxide and silicon dioxide have the same kind of bonding but one is a gas at room temperature whilst the other is a solid. Explain this observation."

Explanation:

Because of their structure . Silica has a  chain structure with e one silicon atom bonded to 4 oxygen atoms in the lattice. The structure is a long chain of tightly held atoms and this forms a solid.

The carbon dioxide molecule however as a linear structure and each  oxygen atom is bonded by double bonds. These double bonds are not as strong as the Si - O bonds in silica so will not form a chain structure.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

it would be a gas formation
