What would happen to an atom in its ground state of external energy was applied to the electrons g

The electron after getting the energy would jump to an orbital further away from the nucleus.  

•Ground state refers to the lowest energy state an atom can be at. When an electron in an atom captivates energy it is considered to be in an excited state.  

•An excited atom becomes unstable and seem to align itself to move back to its lowest energy state.  

•When an atom in its ground state is supplied with an external energy, the energy is absorbed by the atom and the electron becomes excited and jumps to an orbit , that is, distant from the nucleus.  

•It can be said that electron attains higher energy state, with the absorption of more energy by the atom, the electron further moves to higher state till it becomes a free electron and no longer remains the part of the atom.  

Thus, the electron after getting the energy would jump to an orbital further away from the nucleus.

Explanation:

According to Bohr's theory, when external energy is supplied to an atom, its electrons absorb energy and move from a lower energy level to a higher energy level.They quickly return to their original level and re-radiate the absorbed energy as a photo of light.

Hence, when an atom in ground state receives external energy, it becomes excited because energy is transferred to its electrons and they move from lower to higher energy level.
