Atomic radii of some elements in the periodic table are as given below . 152 pm , 186 pm , 231 pm , 244 pm , Do these elements belong to group or period ?

Which of these elements belongs to Group VI A in periodic table?

The atomic radii of the elements across the second period of the periodic table -

Atomic number of an elements is 51, state the period of periodic table to which it belongs.

Atomic number of an elements is 33, state the period of periodic table to which it belongs.

The atomic radii of group 1 elemetns of the periodic table are as follows: Na (186 "pm"), Li (152 "pm"), R(244"pm"),Cs(262"pm") and K(231"pm") . (a) Arrange these element in the increasing order of their atomic radii in a vertical column (keeping the element with the smallest atomic radius at the top). (b) Which elements have the smallest and largest atoms? (c) From this data, infer how the size (or atomic radius) of elements vary as we go doen in the group

Atomic number of an element is 80, state the period of periodic table to which it belongs

Atomic number of an element is 50, state the period of periodic table to which it belongs

Atomic number of an element is 82, state the period of periodic table to which it belongs

Atomic number of an element is 32, state the period of periodic table to which it belongs
