Question

The ground term symbol for Cu2+ ion is​

Answer 1

Answer:

cu is copper and it is positive ion.

Answer 2

Given:

Given species is $Cu^{+2}$.

To find:

The ground state term symbol.

Solution:

From the electronic distribution in the 3d orbital of $Cu^{+2}$, we can see that it has one unpaired electron so, the value of s=1/2.

Thus, the value of 2s+1 is 2.

Now the value of l is as follows-

l=+2+2+1+1-1-1-2

l=2

For l=2 the term is D.

Thus, the value of J is from l+s to l-s.

J=2+1/2 to 2-1/2

J=5/2,3/2.

As $Cu^{+2}$ has more than half-filled, the ground state term has a higher J value and is given as $^{2}D_{5/2}$.

The ground state term symbol for $Cu^{+2}$ ion is $^{2}D_{5/2}$.
