Question

why Atom is Neutral?​

Answer 1

Answer:

A normal atom has a neutral charge with equal numbers of positive and negative particles. That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons.

Answer 2

$answer$

A proton and an electron have an equal amount but an opposite type of charge. Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral.

Any particle, whether an atom, molecule or ion, that contains less electrons than protons is said to be positively charged.
