Multiple Choice

Electrically charged atoms that have gained or lost electrons are called:

Electrical charge appears on an atom when electrons are added or removed. If an atom gains electrons, it becomes negatively charged; if it loses electrons, it becomes positively charged. These charged atoms are called ions. Neutral atoms, with no net charge, are not ions. So the correctly described concept is ions. For instance, a sodium atom can lose an electron to form a positively charged sodium ion, while a chlorine atom can gain an electron to form a negatively charged chloride ion.
