An atom that has gained or lost electrons in an attempt to become stable/bond with another atom.
Normal/Neutral Atom
Ion
Isotope
An atom with the same number of protons and electrons (no charge) and the expected atomic mass or number of neutrons from the periodic table.
Neutral/Normal Atom
Ion
Isotope
A negatively charged ion that has gained electrons to satisfy the octet rule (metals do this)
Anion
Cation
Neutral Atom
Isotope
A positively charged ion that has lost electrons to satisfy the octet rule (non-metals do this)
Anion
Cation
Neutral Atom
Isotope
Atoms of the same element that have different mass than expected because they have a different number of neutrons.
Neutral Atom
Ion
