Carl Nolan · Answer 1

The valence shell has higher energy than other occupied shells

Explanation:

According to Bohr's model of the atom, he suggested that the extranuclear part consists of electrons in specific spherical orbits around the nucleus.

His model suggests that the electron can move round the nucleus in certain permissible orbits or energy levels. The ground state is the lowest energy state available to the electron. The excited state is any level higher than the ground state.

The valence electrons are in the outermost shell of an atom. These electrons are of the highest energy levels in the atom
