Answer 1

Answer:

The main features of modern periodic table

Elements are arranged in the increasing order of atomic numbers.

Elements in the modern periodic table are arranged in 7 periods and 18 groups.

Horizontal rows are called periods and vertical columns are called groups.

Answer 2

Answer:

Important salient features of the modern periodic table.

The modern periodic table has 18 groups 7 periods.

The atomic size of an element increases down the group due to the addition of shells at every unit. whereas the atomic size decreases from left to right along a period due to the increase in nuclear charge.

The metallic character increases down the group and decreases from left to right along a period.

The valency of elements first increases from 1 to 7 with respect to oxygen and 1 to 4 with respect to hydrogen and the decreases to 0 along a period.

The valency remains the same in a group.

The electronegativity of the elements increases along a period since the non-metallic character increases.

similarity it decreases down the group since the non-metallic character decreases.

_______________________________

Separation of elements in different groups and periodicity in their properties explain that the nature of elements depend upon the same type of electronic configuration which verifies that the atomic no. is more fundamental properties on the behalf of which the elements can be classified.
