Introduction:
Multielectron atoms refer to atoms that have more than one electron in their outermost energy level. These electrons interact with each other, which results in complex electronic configurations and energy levels. Understanding the behaviour of multielectron atoms is essential in various fields of science, including chemistry and physics. This essay will discuss multielectron atoms, their electronic configurations, and energy levels.

Electronic Configuration:
The electronic configuration of an atom refers to the arrangement of electrons in its orbitals. The electrons occupy the orbitals based on their energy levels. For multielectron atoms, the electronic configuration is complex due to the interaction between the electrons. The interaction between electrons is known as electron-electron repulsion, resulting in various effects, such as shielding and effective nuclear charge.

Shielding:
Shielding refers to the reduction of the effective nuclear charge experienced by an electron due to the presence of other electrons. Electrons closer to the nucleus experience a higher effective nuclear charge than those further away. The presence of other electrons reduces the effective nuclear charge and hence the energy required to remove an electron from an atom.

Effective Nuclear Charge:
Effective nuclear charge is the net charge experienced by an electron in a multielectron atom. It takes into account the shielding effect of other electrons in the atom. The effective nuclear charge increases as the distance between the nucleus and the electron decreases. As a result, electrons closer to the nucleus experience a higher effective nuclear charge than those further away
