Question

atomic radius goes on decreasing while going from left to right in a period

Answer 1

hey your ans is here
-----
when we move from left to right the nuclear charge increases such that the electrons in outer shell are pulled inwards with great force thus leading to a small size and radius of an atom
------
hope it helps!

Answer 2

Answer:

brainliest please plz

(i) Atomic radius is the distance between the centre

of the atom and its outmost shell.

(ii) Atomic radius decreases across a period.

(iii) This is because valence electrons are being added

to the same outermost shell or to the same energy

level because of which the electrons added

experience greater pull from the nucleus.

(iv) This results in the electrons moving closer to

the nucleus. Hence, the atomic radius goes on

decreasing while going from left to right in a period.
