Solution
The correct option is (A)
Group- 8
Period- 7
There are seven periods and eight groups in Mendeleev's periodic table.
Mendeleev's Periodic Law states that the properties of elements are the periodic function of their relative atomic masses.
Mendeleev arranged all 63 elements (which were discovered till his time) in the order of their increasing relative atomic masses in a tabular form. It is known as Mendeleev’s Periodic Table. He divided the table into eight vertical columns and seven horizontal rows. These columns are known as groups and rows are known as periods.
