Detailed explanation-1: -Ground state: Lowest energy state of any atom or ion is called ground state of the atom. It is n=1. Excited energy (IE): Minimum energy required to move an electron from ground state to n=∞ is called ionisation energy of the atom or ion.

Detailed explanation-2: -The atom, or system, is said to undergo a transition between two energy levels when it emits or absorbs energy. The lowest energy level of a system is called its ground state; higher energy levels are called excited states.

Detailed explanation-3: -The nucleus of an atom is surround by electrons that occupy shells, or orbitals of varying energy levels. The ground state of an electron, the energy level it normally occupies, is the state of lowest energy for that electron. There is also a maximum energy that each electron can have and still be part of its atom.

Detailed explanation-4: -The arrangement of electrons in the atomic orbitals of an atom is called the electron configuration. Electron configurations can be determined using a periodic table. The ground state configuration is the lowest energy, most stable arrangement.

Detailed explanation-5: -The electrons in an atom are arranged in shells that surround the nucleus, with each successive shell being farther from the nucleus. These shells are represented by the letter K, L, M, N, and so on. More items
