An atom that is ionized must have which of the following?
A
More neutrons than protons
B
A net electrical charge
C
A full valence shell
D
An equal number of protons and electrons
Verified step by step guidance1
Understand the definition of an ionized atom: an atom that has lost or gained one or more electrons, resulting in a net electrical charge.
Recall that protons are positively charged and remain constant in the nucleus during ionization, while electrons are negatively charged and can be lost or gained.
Recognize that having more neutrons than protons does not define ionization; neutrons are neutral particles and do not affect the charge.
Note that a full valence shell relates to chemical stability, not ionization; an atom can be ionized regardless of its valence shell configuration.
Conclude that the key characteristic of an ionized atom is having a net electrical charge due to an imbalance between the number of protons and electrons.
