Chapter 23: Q34 P (page 1059)

Which lanthanide has the maximum number of unpaired electrons in both its atom and 3+ ion? Give the number of unpaired electrons in the atom and ion.

Short Answer

Expert verified

Gadolinium has the maximum number of unpaired electrons in both atom and +3 ion

Gb - 8 unpaired electrons

Gb3+ 7 unpaired electrons

Step by step solution

01

Unpaired electron

An unpaired electron is an electron that occupies an orbital of an atom singly, instead of as a part of an electron pair.

02

The number of unpaired electrons in the atom and ion

The lanthanide has the maximum number of unpaired electrons in both its atom and 3+ ion is Gadolinium (Gd) and Electron configurations of Gd is Gb:[Xe]4f75d16s2 and unpaired electrons.

Gb - 8 unpaired electrons

Gb3+ 7 unpaired electrons
