Which of the following is the correct order of size?
Which among the following elements has the largest atomic radii?
- In below ladder symbols of elements are jumbled up. Rearrange these symbols of elements in the increasing order of their atomic number in the Periodic Table.
- Arrange them in the order of their group also.
- Electropositive nature of the element(s) increases down the group and decreases across the period
- Electronegativity of the element decreases down the group and increases across the period
- Atomic size increases down the group and decreases across a period (left to right)
- Metallic character increases down the group and decreases across a period.
