प्रश्न
Give scientific reason.
Atoms are stable though negatively charged electron is revolving within it.
उत्तर
Atoms are stables though negatively charged electrons are revolving within it because each atom contains equal numbers of protons and electrons. So, the charge on negatively charged electrons are balanced by a charge on the positively charged proton. Therefore, the atom is electrically neutral and stable.
