Question

The atomic radii of the element of second period are given below Aaeamfe them in decreasing order of their atomic radii

Answer 1

Answer:

Atomic radii of the elements of the second period are given below:

Explanation:

The elements of second period in the decreasing order of their atomic radii are:

Li Be B C N O

152 111 88 77 74 66

(ii) Yes, the above elements are arranged in the pattern of a period in the periodic table.

(iii) Li has the largest (152 pm) and O has the smallest (66 pm) atoms.

(iv) The atomic radii decrease as we move from left to right in a period due to a corresponding increase in their nuclear charge.
