the correct names of $ca_3n_2$ and $ba_3n_2$ are:

1. calcium nitrogen and barium nitrogen
2. cobalt nitride and beryllium nitride
3. calcium nitride and barium nitride
4. carbon nitride and boron nitride

Explanation:

• For ionic compounds like \(Ca_3N_2\) and \(Ba_3N_2\), the naming rule is: the name of the metal (cation) first, followed by the name of the non - metal (anion) with the suffix “-ide”.
• \(Ca\) is the symbol for calcium, \(Ba\) is the symbol for barium, and \(N\) (as an anion \(N^{3 -}\)) is named “nitride”.

Answer:

1. Calcium nitride and Barium Nitride
