Question

Negative charge in a conductor is a result of: lack of electrons neutralization by the atom's nucleus. surplus of electrons

Answer 1

Negative charge in a conductor is a result of
surplus (too many) of electrons

Answer 2

surplus of electrons

Step-by-step explanation:

Electron is a negatively charged particle and a proton is a positively charged particle.

A neutral atom contains equal number of protons and electrons. Electron can transfer from one atom to another. If an atom loses electrons, it becomes positively charged as the number of protons exceed the number of electrons in the atom. When the atom gains electrons, it becomes negatively charged as the number electrons exceed the number of protons.

Thus, a negative charge in a conductor is a result of surplus of electrons.
