Of the following,the one with the largest size is:

Which of the following radius order is not correct?

Why are the radii of $_{11}Na$ and $_{20}Ca$ larger compared to $_{12}Mg$?

The order of magnitude of ionic radii of ions $Na^{+}$,$Mg^{2+}$,$Al^{3+}$ and $Si^{4+}$ is

The correct order of atomic radii of given elements is

The size of isoelectronic species $F^{-},$ $Ne$ and $Na^{+}$ is affected by
$(a)$ Nuclear charge $(Z)$
$(b)$ Valence principal quantum number $(n)$
$(c)$ Electron-electron interaction in the outer orbitals
$(d)$ None of the factors because their size is the same.
