Final answer:
The formula for Beryllium Nitride is Be3N2.
Step-by-step explanation:
The formula for Beryllium Nitride is Be3N2. Beryllium (Be) has a charge of +2 and Nitride (N3-) has a charge of -3. To balance the charges, you need 3 Be atoms (2x3=+6) and 2 N atoms (3x2=-6). Therefore, the formula for Beryllium Nitride is Be3N2.
