metallic character increases from left to right but increases from top to bottom explain
Answers
Answer:
Metallic character decreases when we go from left to right on the periodic table.
Explanation:
Metallic character in this context depends on the ease with which an electron can be removed from the valence shell of an atom.
When we move from left to right on the periodic table, the number of electrons added to the valence shell increases. When this happens the valence shell get attracted more strongly towards the nucleus. As a result the 'ease' with which the electron is removed decreases. Hence metallic character decreases. (This is also the reason why size decreases as we move from left to right)
As we move down the group, the distance of the valence shell from the nucleus increases. This means that the electrons in the valence shell are not tightly bound to the nucleus. This increases the 'ease' with which the electron can be removed. Hence the metallic character increases down the group.

Answer:
The metallic character of an element ddecreases as you move from left to right or bottom to top of the periodic table.this is because atoms have a better ability to gain electrons to fill a valance shell than lose them to and an unfilled shell. in other words it increases as you go from right to left or top to bottom
