The graph of atomic number (Z) Vs atomic radius (r) is shown in figure

1.	The graph of atomic number (Z) Vs atomic radius (r) is shown in figure 1, 2, 3 and 4 Which graph correctly represents the element of 2^(nd) period and 1^(st) group respectively. choose your options from below.
Answer» 1, 3 1, 4 4, 2 2, 1 SOLUTION : Atomic radius goes on DECREASING with increasing of atomic NUMBER Atomic radius increases with atomic number in a GROUP
