Final answer:
An ion with a charge of +7 is 7 units away from being neutral.
Step-by-step explanation:
An ion with a charge of +7 is 7 units away from being neutral. In order to determine how far an ion is from being neutral, you need to consider its charge relative to the charge of a neutral atom. For example, a neutral atom has an overall charge of 0, so an ion with a charge of +1 is 1 unit away from being neutral. Similarly, an ion with a charge of -3 is 3 units away from being neutral. Therefore, an ion with a charge of +7 is 7 units away from being neutral.
