Question

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

Answer 1

there's a fact behind it that while you go from left to right in period the no. of proton and electron increases
 

Answer 2

Answer:

Explanation:

(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.
