Answer 2

Explanation:

1. In Mendeleev periodic table, vertical columns in the periodic table and horizontal row in the periodic table were named as groups and period respectively.
2. The periodic table is composed of seven horizontal rows or periods and is numbered between 1 to 7.
3. There is a regular gradation in the properties of elements in the horizontal rows(periods) from left to right.
4. The periodic table is composed of eight vertical columns or groups. They are numbered between 1 to 8.
5. If the element is similar but not much, to distinguish between them, it is placed below and slightly away from it. Thus, each column will have two sub-columns A and B, so elements will show more similarity in the same sub-columns.
6. Groups from I to VII are meant for normal elements and group VIII is for transition elements.
7. Groups from I to VII have been divided into two subgroups, while group VIII is meant for three elements.
