Question

which describes an atom that has fewer neutrons than protons and more electrons than protons?
negative compound
positive compound
positive ion
negative ion

Explanation:

• A compound is a substance formed when two or more elements chemically bond together. The question is about an atom, not a compound. So, options "negative compound" and "positive compound" can be eliminated.
• An ion is an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
• A positive ion (cation) is formed when an atom loses electrons (so it has more protons than electrons).
• A negative ion (anion) is formed when an atom gains electrons (so it has more electrons than protons). The number of neutrons compared to protons does not determine if it is a positive or negative ion. The key is the number of electrons relative to protons. Since the atom has more electrons than protons, it is a negative ion.

Answer:

negative ion
