Question

A) Electropositivity of the element increases down the group and decrease across the period. B) Electronegativity of the element decrease down tge group and increase across the period.
C) Electronegativity is directly releted to the non metallic charater.
On the basis of above trend of the periodic talbe ans.the following ques.about the element witj atomic no. 3 to 9.
1)name the most electropositiv element among them
2)name the most electronegative element.
3)which elemet do you expecr to be least electronegative among alkali metals ​

Answer 1

1)3. as it is in left side of the periodic table hence it is a metal and is electropositive 2)90s the most electronegative because it is right side as we know as we move from left to right non metallic character increases 3)3 (lithium)

Answer 2

1) Lithium aka li with atomic number 3

2) Fluorine aka F with atomic number 9

3) Lithium
