Sodium ion will interact with Nh3 or O2

Na interact with oxygen

Chloride will hang out with NH3 why?

Ion	Likes to interact with	Why
Na⁺	Oxygen (O₂)	Oxygen is very electronegative; Na⁺ wants to give up electrons and form a bond.
Cl⁻	Ammonia (NH₃)	NH₃ has slightly positive hydrogens that Cl⁻ can attract.

Sodium ion (Na⁺)

• Na⁺ is positive.
• It wants to find something negative to balance its charge.
• Oxygen (O₂) by itself is neutral (no charge), but oxygen atoms are very electronegative — meaning they attract electrons strongly.
• Na can react with oxygen (especially O₂ gas) to form sodium oxide (Na₂O) — a chemical bond, not just “hanging out.”

So: Na reacts with oxygen, not just hangs out.

Chloride ion (Cl⁻)

• Cl⁻ is negative.
• It wants to find something positive to balance its charge.
• NH₃ (ammonia) is neutral, but the nitrogen in NH₃ has a slightly negative side, while the hydrogens have a slightly positive side (because of how the molecule is shaped — it’s a “polar molecule”).
• Cl⁻ can weakly interact with the slightly positive hydrogens in NH₃.

So: Cl⁻ hangs out with NH₃ because NH₃ has slightly positive hydrogens, even though NH₃ is not fully charged.
