Answer:

The answer to your question is   Rb₃N

Explanation:

Data

Lithium Nitride = Li₃N

Rubidium Nitride = ?

Process

1.- Both Lithium and Rubidium are placed in group lA of the periodic table, which means that their valence number if + 1.

2.- Nitrogen is placed in group VA, which means that its oxidation number is -3.

3.- Write the formula and interchange the oxidation numbers.

                                  Rb⁺¹   N⁻³

                                  Rb₃N₁

But number one is not necessary to write it.

                                  Rb₃N
