There are eight third period transition elements on the periodic table.
There are currently 118 known elements in the periodic table.
Period 1: 2 elements Period 2: 8 elements Period 3: 8 elements Period 4: 18 elements Period 5: 18 elements Period 6: 32 elements Period 7: 25 elements
The fourth period contains 18 elements beginning with potassium and ending with krypton – one element for each of the eighteen groups. It sees the first appearance of d-block (which includes transition metals) in the table. Do You Agree? Sincerely, Jocelyn E.Flowers
The periodic table has seven periods. Each period corresponds to the principal energy levels of electrons in the atoms of the elements within that row. As you move down the table from period to period, the elements have increasing atomic numbers and greater complexity in their electron configurations.
There are 32 elements in the 6th period of the periodic table.
There are 8 elements in the third period of periodic table. The elements belong to group-1,2,13,14,15,16,17 and 18
There are eight third period transition elements on the periodic table.
There are 2 elements in the first period, 8, 8 elements in 2nd and 3rd periods respectively,
There are currently 118 known elements in the periodic table.

There are 18 elements in period 4 of the periodic table, corresponding to 4 shells.
The fourth period contains 18 elements beginning with potassium and ending with krypton – one element for each of the eighteen groups. It sees the first appearance of d-block (which includes transition metals) in the table. Do You Agree? Sincerely, Jocelyn E.Flowers
