Question

ionic and covalent nomenclature brittany kessler multiple - choice question what is the charge of fe based on this chemical formula? 2- 2+ 1+

Explanation:

Step1: Identify bromide ion charge

Bromide ion ($Br^-$) has a charge of 1-.

Step2: Determine iron charge

In $FeBr_2$, there are 2 bromide ions. Total negative charge from bromide is $2\times(1 -)=2 -$. For the compound to be neutral, iron ($Fe$) must have a 2+ charge to balance the 2 - charge from bromide ions.

Answer:

2+
