Question

use the drop - down menus to complete the statements. when electrons are lost, a ion is formed. when electrons are gained, a ion is formed.

Explanation:

Atoms are electrically neutral as they have equal numbers of protons (positive charge) and electrons (negative charge). When an atom loses electrons, the number of protons exceeds the number of electrons, resulting in a positive charge. Such ions are called cations. When an atom gains electrons, the number of electrons exceeds the number of protons, resulting in a negative charge. Such ions are called anions.

Answer:

When electrons are lost, a cation ion is formed.
When electrons are gained, an anion ion is formed.
