What is the ground-state electronic configuration for zinc?

Hint: The electronic configuration of an element is going to explain the presence of electrons in the orbitals. If the atom is in an excited state, then the electronic configuration of the atom is called excited electronic configuration and vice versa.
Complete step by step answer:
- In the question it is asked what the ground state electronic configuration for zinc is.
- To write the electronic configuration of zinc, first we should know the atomic number of zinc.
- The atomic number of Zinc is 30.
- We know that the atomic number of an element gives the information about the number of electrons present in that atom.
- Means the number of electrons in zinc are 30.
- So, by using the number of electrons we can write the electronic configuration of an element.
- The zinc atom is neutral in state at room temperature, so zinc is in its ground state.
- The ground state electronic configuration of zinc is $1{s^2} 2{s^2} 2{p^6} 3{s^2} 3{p^6} 4{s^2} 3{d^{10}} $ .
- The element zinc is belonging to d-block and has fully filled orbitals and it is very stable in nature because of filled electrons in the atomic orbitals.

Note:
Every element is going to have gone to have ground state electronic configuration in their stable form. In an excited state the atoms are going to have a different electronic configuration when compared to the atom which is in ground state. In an excited state the electrons are going to exist in the atoms in a different way.
