Why atom is electrically neutral ?

An atom is electrically neutral because it has an equal number of positively charged protons in its nucleus and negatively charged electrons surrounding the nucleus. The positive charge of the protons is balanced by the negative charge of the electrons, resulting in an overall neutral charge for the atom.

An atom is electrically neutral because the number of protons in the nucleus is equal to the number of electrons orbiting the nucleus. Protons have a positive charge, while electrons have a negative charge. The equal number of protons and electrons in an atom cancels out the charges, resulting in an overall electrical neutrality.
