Interpretation Introduction

Interpretation:The expected length of rows in periodic table if $g$ and $h$ orbital existed should be written.

Concept introduction:There are four quantum numbers that serve basis of quantum aspects related to size, position, orientation, and spin associated with an electron.

Principal quantum number depicted as $n$ determines size and energy of a particular shell. It may have values from $n=1,2,3$ and so on.

Azimuthal quantum number describes shape and determines orbital angular momentum associated with a particular orbital. It is characterized by values $l$ equal to 0 for s-orbital, $l$ equal to 1 for p-orbital, $l$ equal to 2 for d-orbital and $l$ equal to 3 for f-orbital orbitals and so on.

Magnetic quantum number determines orientation of certain orbital. Its values range from $-l$ to $+l$ . Each of such orbital gas quantized values of angular momentum that is determined from values of $l$ .

Spin quantum numbers help to predict intrinsic spin associated with electron. It can take only two values $m_s$ equal to $+\text{1/2}$ or $m_s$ equal to $-\text{1/2}$ .

Each orbital has accommodated only two electrons.
