Question

question 8 1 pts which of the following combinations of atoms would form ionic bonds? po4 - and i2 - na+ and cl - na+ and k+ h+ and o

Explanation:

Ionic bonds form between a cation (positively - charged ion) and an anion (negatively - charged ion). Sodium ($Na^+$) is a cation and chlorine ($Cl^-$) is an anion. $PO_4^-$ and $I_2^-$ are both anions, $Na^+$ and $K^+$ are both cations, and $H^+$ and $O$ do not form a stable ionic - bond combination in the way presented.

Answer:

$Na^+$ and $Cl^-$
