Answer 1

Answer:

The group number in the periodic table represents number of valence electrons of the elements in a certain group.

Answer 2

Answer:

The group number in the periodic table indicates the number of valence electrons of a particular element i.e the number of electrons present in its outer most shell. But this is valid only for the s block elements.

For the p block elements, the group number will be 10 + valence electrons.

In general it can be said that the group number indicates the number of valence electrons.
