Question

The charge on the polyatomic ion, NO₂, is 1-. What will be the formula of one formula unit of acompound between NO₂ and Be?

Answer 1

The formula of one formula unit of the compound between NO2 and Be is Be(NO2)2.

Step-by-step explanation:

The charge on the polyatomic ion, NO2, is 1-. To determine the formula of a compound between NO2 and Be, we need to balance the charges of the ions involved. Beryllium has a charge of +2, so we need two NO2 ions to balance the charge.

The formula of one formula unit of the compound between NO2 and Be is Be(NO2)2.
