When a cation forms, more electrons are transferred to it

Explanation:

Ions can either be cations (positively charged species) or anions (negatively charged species).

Cations are produced when atoms, typically metal atoms, lose their valence electrons to become positively charged.

Anions are produced when nonmetal atoms gain electrons to become negatively charged.

These definitions already eliminate the majority of choices: cations are positively charged ions. Anions are common among nonmetals.

Thinking about nomenclature, charges are represented by a superscript of a number with either a plus (for positive charges) or a minus (for negative charges).

It is false, however, that when a cation forms, electrons are transferred to it. In reality, cations lose electrons rather than gain.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
