increasing size of ions - F⁻ < O²⁻ < N³⁻
When an atom tends to gain electrons then it acquires a negative charge. This means that size of the atom increases.
So, more is the negative charge present on an atom more will be its atomic size. Therefore, correct order of increasing size for O²⁻, F⁻, N³⁻ is as follows -
F⁻ < O²⁻ < N³⁻
In the periodic table, atomic radii decrease from left to right across a row and increase from top to bottom down a column. Because of these two trends, the largest atoms are found in the lower left corner of the periodic table, and the smallest are found in the upper right corner
