Answer:

The decreasing order of these elements are as follows:

Be: 1.4 A°

C: 0.91 A°

F: 0.57 A°

Ne: 0.51 A°

These elements belong to same period in the periodic table

The simple logic that follows is, as we go from left to right of a period, elements are arranged in manner of increasing order of their atomic number. The number of shells remaining constant in a period, the nuclear force increases and the valence electrons are attracted more inwardly. Hence there is a decrease in atomic size of the elements in same period.

Hope it helps
