Consider the following representation based on long form of periodic table.

Value of al four quantum number for last electron of element 'X' in their ground state is
`n=4,l=1,m=1 and s=-(1)/(2)` and spin mutiplicity of element 'X' in their ground state is 4.
Q. Which of the following order is incorrect?

Options

A. Magnetic moment `U gt V gt A`
B. Atomic radius: `E gt X gt T`
C. Ionisation energy `: R gt X gt B`
D. Stability: `F^(3+) lt E^(3+) lt X^(3+)`

Answer

D
