# What is the ion notation for an atom with 34 protons and 36 electrons?

$Z$ $=$ $34$, therefore the atom is selenium.
While the number nuclear protons as given is 34, and therefore we deal with the element selenium, there are 2 more electrons than protons, and therefore this species has an overall $2 -$ charge.
We represent this selenide ion as $S {e}^{2 -}$. Do I win 5 pounds?
