Question

The electrical charge of an atom with equal number of protons and electrons will be _________.

• A. 1
• B. -1
• C. 0.0
• D. 2

Answer 1

The correct option is C 0.0

Atoms have electrons, protons, and neutrons as the fundamental particles. Proton carry a unit positive charge and electron carry a unit negative charge while neutrons are neutral. A neutral atom has always an equal number of electrons and protons. So the total charge due to electrons and protons balance out.
Hence, the charge on the atom is zero, i.e. no net charge.
