Question

(b), Metallic character goes on
decreasing while going from left to
right in a period.​

Answer 1

Explanation:

metallic character decreases when we go from left to right because metals are highly electropositive (meaning they have tendency to lose electrons to complete their octet). As we move from left to right the elements stay to gain electrons which makes it easier to gain electrons rather than to lose electrons to complete it's octet. So this type of properties of losing the electrons is only present in non metals. Hence the metallic property decreases as we move from left to right.

hope you will understand and if any doubts feel free to ask it in the comments. please mark it as the brainliest.

Answer 2

Answer:

The number of electrons increases from left to right , thereby increasing nuclear charge, also the size goes on decreasing therefore the tendency to attract electrons increases , hence increasing the amount of non metallic trait.
