Q6ChemistryUnit 9: Classification of Elements and Periodicity in Properties
The graph below shows the atomic radii of atoms in picometers (pm)(\mathrm{pm}) as a function of atomic number. Which letter on this graph most closely shows the location of the transition metals of period 5? Atomic Radius vs. Atomic Number
Q7ChemistryUnit 9: Classification of Elements and Periodicity in Properties
Assertion Atomic size decreases in a period due to increase of atomic number. Reason The nuclear charge is increasing and size of valence shell remains same as we move from left to right. Hence, in any period, the atomic size of the element decreases from left to right.
