What is an example of ground state?
The ground state is the state that is occupied by the most part of the atoms of the same element at room temperature, because it is lower in energy. … For example, a simple six electron atom as the carbon atom has the most stable electronic configuration represented by 1s² 2s² 2p².
What is Hund rule?
Hund's Rule. Hund's rule: every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
