Answer 2

•Increasing order of their atomic radii.

=O>N>C>B>Be>Li

• yes, they are arranged like a

period in inverse order

•Largest atom is Lithium (Li)

Smallest atom is Oxygen(O)

•The atomic size generally decreases

across a period. It is bcoz within the

period the outer electrons are in the

same valance shell and the effective

nuclear charge increases as the

atomic number increases resulting in

the increased attraction of the

elections to the nucleus.
