Answer :
Answer:A
Explanation: ion
an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
Answer:
Option A) Atoms have lost or gained an electron and have a charge
Explanation:
The result of a loss or gained electron can cause a large or lesser number of protons than the electrons, which causes a charge imbalance because protons have a positive charge and electrons have a negative charge. If the number of protons or the number of electrons is unequal, then it means that the atom has a charge, and is an ion. It is a cation if it lost an electron such that it has a positive charge and it is an anion if it gained an electron such that it has a negative charge.
