Question

Calculate the four quantum values of 4p6 for 5th electron. Ask

Answer 1

Four quantum values for 4p⁶ 5th electrons are- n= 4, l = 1, m = -1, s= +1/2 or -1/2.

• There are four quantum numbers- n, l, m, and s
• n, which is the principal quantum number. Its value denotes the shell.
• l, is the azimuthal quantum number. Its value is 0 to n-1.
• l is 0, 1, 2, 3 for s, p, d, and f -subshells respectively.
• s, is the spin quantum number which can be +1/2 or -1/2
• m, is the magnetic quantum number its value is -l to +l.

• In 4p⁶, n is 4, l is 1 as it belongs to the p-subshell that has l = 1.
• And, the 5th electron of 4p⁶ enters the 4pₓ orbital of the p-subshell.

• pₓ orbital's m value is,m = - 1.
• Its spin number can be, s = +1/2 or - 1/2.
