Question

Significance of four quantum number

Answer 1

$\boxed{\sf \green{Quantam \: Numbers}}$

• To determine the position of an electron in an atom.. quantam numbers are required.
• The quantam numbers are derived from Schrondinger'sequation
• There are 4 types f quantam numbers

$\texttt{\green{1. Principal\: quantam\: Number (n)}}$

• It was proposed by Neil's Bohr

• It is denoted by "n"

• n = 1,2,3,4... or K,L,M,N.....

• Maximum number of electrons in the main shell is given by 2n²

Significance:

• It describes about the orbit. As the value of 'n' increases, size and energy of orbit also increases

$\texttt{\red{2.Azimuthal\: quantam\: Number (l)}}$

• It was proposed by Sommerfeld

• It is denoted by "l"

"• l = 0, 1,2,3,... or s,p,d,f.....

• It is also called as Angular Momentum quantam number

• It represents the sub-levels in the shells

Significance:

• It describes the shape of subshells or levels

$\texttt{\pink{3. Magnetic\: quantam\: Number (m_l)}}$

• It was proposed by lande

• It is denoted by "m"

• m has values ranges from -l to +l

• It represents the orientation of orbitals in space

Significance:

• It describes the orientation of orbitals in the space

$\texttt{\orange{4. Spin\: quantam \: Number (m_s)}}$

• It is denoted by "s"

• S has values +1/2 and -1/2

• +1/2 describes Clock wise and -1/2 describes the Anti-clockwise Direction of spin

Significance:

• It describes the direction of spin of electron
