HEEYEE MATE ❤️❤️❤️❤️ HERE IS UR ANSWER....
WHEN WE GO FROM LEFT TO RIGHT IN A PERIODIC TABLE ATOMIC RADIUS SIZE DECREASE... THIS IS BECAUSE THE NUCLEAR FORCE OF ATTRACTION INCREASES AS THE NUMBER OF ELECTRONS KEEPS ON INCREASING BUT THE NO. OF SHELLS REMAINING THE SAME...
WHEN WE GROW FROM TOP TO BOTTOM TO KNOW THE SIZE OF ATOMIC RADIUS INCREASES THIS IS BECAUSE THE NUCLEUS FORCE OF ATTRACTION DECREASES AS THE NUMBER OF CELLS INCREASES TOP TO BOTTOM AND THE OUTERMOST ORBIT ELECTRONS REMAINS THE SAME....
HOPE THIS WILL HELP YOU ❤️ ❤️❤️❤️
STAY BLESSED ❤️ ❤️❤️

Two elements 'p' and 'q' belong to the same period of the modern periodic table and are in group -1 and group -2 respectively compare the following characteristics (a) the number of valence electrons in their atom(b) formula of their oxides (c) formula if there chlorides

From left to right atomic radius decreases because because the electrons are added to same shell due to this they experience a great force from the nucleus.
While atomic radius increases in group from top to bottom cause new shells are added and the electrons are bring away from the nucleus.
