Final answer:
The correct formula for the compound formed between beryllium and nitrogen is Be3N2, as it balances the +2 and -3 charges of beryllium and nitrogen ions, respectively.
Step-by-step explanation:
The correct formula for the compound formed between beryllium and nitrogen is Be₃N₂.
In this compound, beryllium has a charge of +2, while nitrogen has a charge of -3. The charges must balance out in the compound, so we need three Be²⁺ ions to neutralize two N³⁻ ions, resulting in the formula Be₃N₂.
To determine the correct formula for the compound formed between beryllium and nitrogen, we need to consider the charges of the ions that form the compound. Beryllium (Be) forms a +2 cation (Be++), while nitrogen (N) forms a -3 anion (N+++-) when they form ionic compounds.
To balance the charges, we need two +2 beryllium ions to balance with three -1 nitrogen ions, which results in the formula Be3N2. This makes option c the correct choice for the compound formed between beryllium and nitrogen. The formula is Be3N2 because the total positive charge from the three beryllium ions (+6) balances out the total negative charge from the two nitrogen ions (-6).
