Question

Give scientific reason of atom are stable though negatively charged electron are revolving within it

Answer 1

the reason itself is the revolution and the spin of electrons in the atom , as it revolves it counterbalances the centripetal force(with centrifugal forces of the electron) thereby making it stay in the same place ie. equidistant from the nucleus at any point of time , therefore preventing the atom from collapsing.... and the spin of the electron counter balances the reverse spin of the other electron in the subshell

Answer 2

The atom has a positively charge nucleus where aroumd which the electron are revolving around it as it has negatively charge, still the atom is stable beacuse the electron experience two forces. one is force of attraction toward nucleus (centripetal force.) and other force is due to its velocity which is acting outward the aton (centrifugal force) thus the two forces balace the electron
