1.	Elements X, Y and Z have atomic numbers 7,15 and 33 respectively. Which of the following statements is correct?
Answer» ATOMIC size of X is greater than that of Y atom. Order of ionic size is `X^(-) gt Y^(-) gt Z^(-)` Z element has bigger atomic size Atomic size of element X is between atomic sizes of elements Y and Z. SOLUTION :Z element has bigger atomic size. X, Y and Z are elements of same group `1S^(th)`: "Atomic size increase from top to bottom in a group".
