Question

1. what is the charge of an ion that has gained one or more electrons?

options: zero, negative, neutral, positive

Explanation:

An atom is neutral with equal protons (positive charge) and electrons (negative charge). When an ion gains electrons, the number of negative - charged electrons exceeds the number of positive - charged protons. So the overall charge of the ion becomes negative. For example, a chlorine atom (Cl) has 17 protons and 17 electrons. When it gains 1 electron, it becomes a chloride ion (Cl⁻) with 17 protons and 18 electrons, and the charge is - 1 (negative).

Answer:

Negative (the option with "Negative" text)
