Detailed explanation-1: -The answer is anion. Anion is the term used to describe a negatively-charged ion where there are more electrons than the number of protons in the atom.

Detailed explanation-2: -Objects with more electrons than protons are charged negatively; objects with fewer electrons than protons are charged positively.

Detailed explanation-3: -A negative ion is an atom or molecule that has more electrons than protons, giving it a net negative charge.

Detailed explanation-4: -When an object has a positive charge, it has more protons than electrons. Therefore, when an object has a negative charge, then that object contains more electrons than protons.

Detailed explanation-5: -Answer and Explanation: An atom that has more protons than electrons is called a cation. Ions are charged atoms or combinations of atoms.
