30 Multiple Choice Questions

1. Which subatomic particle has a positive charge and is located in the nucleus?
ly ly ly ly ly ly ly ly ly ly ly ly ly




a) Electron
ly




b) Neutron
ly




c) Proton
ly




d) Positron
ly




Answer: c) Proton ly ly




Explanation (4 lines): Protons are positively charged particles found in the atomic
ly ly ly ly ly ly ly ly ly ly ly




nucleus. Their number defines the atomic number (Z) of an element. Electrons are
ly ly ly ly ly ly ly ly ly ly ly ly ly




negative and orbit the nucleus; neutrons are neutral. Positrons are antimatter
ly ly ly ly ly ly ly ly ly ly ly




counterparts of electrons.

2. The atomic mass number (A) is the sum of:
ly ly ly ly ly ly ly ly ly




a) Protons and electrons
ly ly ly




b) Neutrons and electrons
ly ly ly




c) Protons and neutrons
ly ly ly




d) Protons, neutrons, and electrons
ly ly ly ly




Answer: c) Protons and neutrons
ly ly ly ly




Explanation: Atomic mass number A = number of protons (Z) + number of neutrons (N).

Electrons have negligible mass and are not counted in A. This distinguishes isotopes
ly ly ly ly ly ly ly ly ly ly ly ly ly




(same Z, different N). A appears as the superscript in nuclide notation (e.g., ¸µCo).
