Final answer:
The atomic radius generally increases from right to left and from top to bottom on the periodic table. In the given ranking, N (nitrogen) has the largest atomic radius, and F (fluorine) has the smallest atomic radius.
Step-by-step explanation:
The correct answer is option C. N > Ne > Na > B > F.
The size of atom refers to the atomic radius, which is the distance from the nucleus to the outermost electron shell. The atomic radius generally increases from right to left and from top to bottom on the periodic table.
In the given ranking, N (nitrogen) has the largest atomic radius because it is located above Na (sodium) in the same group. Ne (neon) is smaller than N because it has a completely filled electron shell. Na is smaller than N because it has one less electron shell. B (boron) is smaller than Na because it is located to the left of Na. F (fluorine) is the smallest atom because it is located at the rightmost side of the period.
