D

Verified step by step guidance1
Understand that atoms are defined by their number of protons, which is called the atomic number and determines the element.
Recognize that atoms with the same number of protons but different numbers of neutrons are called isotopes, which differ in mass but have no charge difference.
Know that allotropes refer to different structural forms of the same element in the same physical state, such as diamond and graphite for carbon.
Identify that isomers are molecules with the same molecular formula but different arrangements of atoms, a concept from organic chemistry, not atomic structure.
Conclude that atoms with the same number of protons but different electrical charges (due to loss or gain of electrons) are called ions.
