Normally, atoms are electrically neutral because there are__.

more protons than electrons

more electrons than protons

equal numbers of protons and neutrons

equal numbers of protons and electrons

Equal number of protons and electrons

Explanation:

This principle of proton and electron equality was used by J.J. Thompson in the discovery of proton. After he had discovered the electron. He discovered that since atoms are electrically neutral, that means there must be equal number of protons to balance out the electrons present in the atom.

we need to know the time interval during which the force acts. impulse of force = momentum change
