Question

(1) Why do alumic radius
decreases left to right?
(2.) Why do clictronegative
character Increases left
to right?​

Answer 1

As you move across a period, the atomic radius decreases, that is, the atom is smaller. The outer electrons are closer to the nucleus and more strongly attracted to the center. Therefore, it becomes more difficult to remove the outermost electron.

$\large\mathcal{\red{Answer :-}}$

The positively charged protons in the nucleus attract the negatively charged electrons. As the number of protons in the nucleus increases, the electronegativity or attraction will increase. Therefore electronegativity increases from left to right in a row in the periodic table.

Answer 2

Answer:

The positively charged protons in the nuclues attract the negatively charged electrons.
