The ionic radius of tetrafluoroborate ion (BF4-) is approximately 1.70 Å (angstrom). This ion is an anion formed by the combination of a boron atom and four fluorine atoms. The size of the ion is influenced by the balance between the attraction of the positive nuclear charge and the repulsion between the electrons in the outer electron shell.

How does ionic radius differ from atomic radius?

Ionic radius is the size of an ion after it has gained or lost electrons, leading to a change in the electron configuration and thus its size. Atomic radius refers to the size of an atom, typically measured as the distance from the nucleus to the outermost electron shell. Ionic radius is affected by the change in electron configuration, while atomic radius is more related to the position of the outer electrons in the neutral atom.


Why does the ionic radius of N3 than that of O2-?

The ionic radius of N3- is larger than that of O2- because the extra electron in the N3- ion is located in a higher energy level, leading to larger electron-electron repulsions and an increase in the ionic radius. Additionally, the effective nuclear charge experienced by the electrons in the N3- ion is lower than that in the O2- ion, further contributing to the larger ionic radius of N3-.

Which one has the larger radius potassium ion or bromide ion?

The bromide ion has a larger radius than the potassium ion. This is because bromine has more electron shells than potassium, resulting in a larger atomic radius and thus a larger ionic radius for bromide compared to potassium.
