how does the atomic radii of the element change in a group?

Because as we move left to right atomic no. Increases and effective nuclear charge increses that'swhy atomic radius decreases and when we go down the group atomic no. Increses and also no. Of shells increases thatswhy effective nuclear charge decreases so atomic radius increases down the group... Hope this one is useful...
allysaltamash14:
increases
also down the group
and so down the group also increases
yeeh as uh can see helium and sodium and potassium atomic no.
but when left to right atomic no. increases the atomic radius decreases
yeeh bro read my ans carefully.... i hv written the reason for this
and doen the group when atomic no oncreases atomic no also increases
bro... down the group atomic no increases as well as atomic radii aslo increses because increasing of no. of shells which reduce the z effective nuclear chrge... got it
kk thx soo much

because when we going downward in the group of periodic table the size of elements increases and effective nuclear charge decreases... so, the atomic radii of the element change in a group....
