Question

In a group, metallic character .....and non-metallic ....... from top to bottom.

Answer 1

Hint: The chemical elements which are going to lose electrons very easily are called metals and the chemical elements which are not going to lose the electrons are called non-metals. In the periodic table all the elements are not metals and all the elements are not non-metals.

Complete answer:
- In the question it is asked the metallic character and the non-metallic character trends from top to bottom in the groups of the periodic table.
- As we know that s-block elements are metallic in nature and the p-block elements are non-metallic in nature.
- But here we must write about the trends of metallic and non-metallic character while moving from top to bottom in the periodic table.
- First, we will discuss the trend of metallic character while moving from top to bottom.
- As we are moving from top to bottom in the groups the size of the atom is going to increase, and the metallic character is also going to increase.
- While coming to non-metallic character, as we are moving from top to bottom in the groups the non-metallic character is going to decrease.
- Therefore, in a group metallic character is going to increase and the non-metallic character is going to decrease from top to bottom.

Note:
The non-metallic character is going to increase while we are going to move from left to right in the periodic table through the periods. In the same way the metallic character is going to decrease as we are going to move from left to right in the periodic table.
