To determine:
The electron configuration of
Concept introduction:
- Electronic configuration of an atom shows how electrons are placed in the orbitals in order of increasing energy.
- The filling of the sublevels progresses in order up to Period 4. However, in the sublevel blocks in Period 4 the 4s sublevel fills before the 3dsublevel.This occurs because the electrons in the 4ssublevel have slightly lower energy than the electrons in the 3d sublevel. This series of 10 elements is called the first transition series (3d).
- 3d elements show large variation in their oxidation states.

Answer to Problem 20.1P
Solution:
:
Explanation of Solution
The arrangement of atomic orbitals in increasing order of their energies is as follows:
The maximum occupancy of electrons for
Thus, electronic configuration will be:
Now, electrons are first removed from
Thus, the electronic configuration of

Solution:
Explanation of Solution
Atomic number of copper is 29. Thus, it has 29 electrons in its elemental state. The arrangement of atomic orbitals in increasing order of their energies is as follows:
The maximum occupancy of electrons for
Thus, the electronic configuration will be:
This is because half filled, and full filled orbitals are more stable.
Chlorine has an oxidation state of -1, thus in
Now filling up 27 electrons of
