State the Aufbau principal ?
Answers
Answer:
The aufbau principle, from the German Aufbauprinzip, also called the aufbau rule, states that in the ground state of an atom or ion, electrons fill subshells of the lowest available energy, then they fill subshells of higher energy. For example, the 1s subshell is filled before the 2s subshell is occupied.
Explanation:
Characteristics of Aufbau Principle
According to the principle: Electrons first occupy orbitals with the lowest energy. The order in which orbital energy increases can be determined using the rule (n+l), where n is the main quantum number and l is the azimuthal numbers.

Explanation:
the afbau principle state that in the ground state of an atom an electron enters the orbital with lowest energy first and subsequent electron are fed in the order of increasing energy
