Question

Period
Elements (Their atomic
radius in pico meter)
2 nd period
Li (152) , Be (111), B (88), C(77),
N (74) 0 (66) F (64)
observe the table and write the
trend of atomic radius in periods.
Also write the reason
briefly.​

Answer 1

Answer:

in a period the atomic radii decreases as we go left to right

this is because as we go left to right in a period the electrons present in the atom increase so the protons in nucleus also increase that means more nuclear charge is applied on the outer most shell so the valence shell is attracted towards the nucleus and the atomic radii become smaller

I think this is the answer..........I hope this helps u
