The period number is 4 and the group number is 6 of the element with the atomic number of 24.
- The electronic configuration of the element with 24 electrons is:
1s2, 2s2, 2p6, 3s2, 3p6, 4s1, 3d5.
- Period no = Principal quantum no = 4
- Group No = The no of electrons more than the noble gas configuration = 6
- So, the element is Chromium which belongs to the Fourth period and the Sixth group.
