Find the Number of Protons Rn

To find the number of protons in ${\displaystyle \text{radon}}$, first locate the element on the periodic table. Next, find the atomic number which is located above the element\'s symbol. Since ${\displaystyle \text{radon}}$\'s atomic number is ${\displaystyle 86}$, ${\displaystyle \mathrm{Rn}}$ has ${\displaystyle 86}$ protons.
