In an ion with an unknown charge, the total mass of all the electrons was determined to be 2.19 ✕ 10−26 g, while the total mass of its protons was 4.34 ✕ 10−23 g. what is the identity and charge of this ion? (enter your answer in the form x^q±.)

Explanation:

1. Number of electrons

2. Number of protons

3. Identify the ion

An atom with 26 protons is iron, Fe.

A neutral atom of iron would have 26 electrons.

The ion has only 24 electrons, so it has lost two. The ion must have a charge of +2.
