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:

1. First, recall the definitions:

• A compound is a substance made of two or more different elements chemically bonded, so "negative compound" and "positive compound" are incorrect as the question is about an atom (or ion), not a compound.
• An ion is an atom (or group of atoms) with a net electric charge due to loss or gain of electrons.
• A positive ion (cation) has more protons than electrons (loses electrons).
• A negative ion (anion) has more electrons than protons (gains electrons).
• The number of neutrons vs protons doesn't affect the charge type here, but the electron - proton ratio does. Since the atom has more electrons than protons, it has a negative charge, so it's a negative ion.

Answer:

D. negative ion
