Choose the correct statement from the following based on iso electronic species. $\mathrm{H},{\mathrm{Li}}^{+2},{\mathrm{Be}}^{+3}$

The size of the ions initially increases then decreases

The ionic radius is decreases from left to right

${\mathrm{r}}_{{\text{Be}}^{\text{+3}}}>{\mathrm{r}}_{{\text{Li}}^{\text{+2}}}>{\mathrm{r}}_{\text{H}}$

All species have same radius
