# The atomic number of element next to $_{53}I$ in the same group is

$\begin{array}{1 1}61\\71\\85\\93\end{array}$

The element $_{53}I$ belongs to the $5^{th}$ period and group 17.Its atomic number can be computed by adding the numbers 2,8,8,18 and 17.The next element will have atomic number 85(=53+32)
