_ are such nuclei of an element that have the same atomic number Z, but have different mass number.
Correct answer: A. Isotopes
- A. Isotopes
- B. Isobars
- C. Isomers
- D. Isotherms
Explanation
Correct option is A. Isotopes of an element has the same number of protons but different numbers of neutrons. Every element has its own number of isotopes.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
