If the atomic number of an atom is 30 and its atomic mass 65.38 then the of electrons in a neutral atom is

30 electrons

Explanation:

Atoms are made of electrons, protons and neutrons.Protons and neutrons are in the nucleus and electrons are orbiting in energy shells around the nucleus. Atomic number is the number of protons and atomic number is characteristic for the element.

protons are positively charged and electrons are negatively charged. Neutral atoms are when the number of protons and electrons are equal.

Therefore this atoms atomic number is 30 where the number of protons is 30, and in the neutral atom since the number of protons is equal to the number of electrons, the number of electrons is 30
