Of the 3 elements nitrogen , oxygen , and aluminum, what is the atomic number of the one that has the smallest atomic radius?

I reposted because i messed up you need to just stop spamming :l

I agree with Ray.

To determine the atomic number of the element with the smallest atomic radius among nitrogen (N), oxygen (O), and aluminum (Al), we need to compare their atomic numbers.

Atomic number represents the number of protons in the nucleus of an atom. Since the atomic radius generally decreases across a period or row of the periodic table from left to right, the element with the smallest atomic number will likely have the smallest atomic radius.

The atomic numbers of nitrogen, oxygen, and aluminum are 7, 8, and 13, respectively. Hence, the element with the smallest atomic number, and consequently the smallest atomic radius, is nitrogen (N) with an atomic number of 7.
