When an ion has a charge of -3, this means that the atom gained 3 electrons .

Question

BlackTom AI · Accepted Answer

The statement provided is: 'When an ion has a charge of -3, this means that the atom gained 3 electrons.'

First, consider the meaning of a negative ionic charge. A negative charge on an ion indicates an excess of electrons relative to protons, meaning electrons were gained during ion formation rather than lost.

Next, quantify what -3 implies. A -3 charge corresponds to three more electrons than protons in the atom, i.e., the atom gained three electrons. This aligns with the basic rule that negative charges arise from electron gain, while positive charges arise from electron loss.

In this particular item, the two blanks filled by the answers are 'gained' and '3 electrons.' The phrasing 'gained 3 electrons' matches the physical interpretation of forming a -3 anion, so these selections correctly convey the concept.

Potential misconceptions to watch for: some might confuse charge sign with oxidation or with losing electrons; remember that a negative charge cannot result from losing electrons, and is instead a result of adding electrons.

Overall, the statement is consistent with standard atomic and ionic behavior: a -3 charge means the atom gained three electrons.
