Question

define aufbau principle and give its one use.??​

Answer 1

Answer:

Aufbau/Afbau..principle states that in the ground state of an atom the electrons are added to the various orbitals of an atom in order of increasing energy starting with orbital of lowest energy.

Uses = it is used for writing electronic configuration of elements

Answer 2

Hey Dugu(◍•ᴗ•◍)❤

Statement:

The Aufbau principle dictates the manner in which electrons are filled in the atomic orbitals of an atom in its ground state. It states that electrons are filled into atomic orbitals in the increasing order of orbital energy level. According to the Aufbau principle, the available atomic orbitals with the lowest energy levels are occupied before those with higher energy levels.

Use:

The Aufbau principle can be used to understand the location of electrons in an atom and their corresponding energy levels.
