Expert Answer

Step 1

An orbital is a region of space in which electrons are filled.  It can hold up to two electrons.

An atomic orbital is the region of space in which the probability of finding the electrons is highest.  It is subdivided into 4 orbitals such as s, p, d and f orbitals which depend upon the number of electrons present in the nucleus of a particular atom.

Aufbau principle: In the ground state of an atom, an electron enters the orbital with lowest energy first and subsequent electrons are fed in the order of increasing energies. The word 'Aufbau' in German means 'building up'. Here, it refers to ...
