If you look at the periodic table, Krypton has an atomic number of 36. Krypton is one of the noble gases. They are a group of elements that are very stable because they obey the Octet Rule. As a result, other elements try to conform the electronic configurations of the nearest noble gases to them. They either give or take electrons in their valence shell.
The three atoms that have 36 electrons are: Kr (Krypton), Br⁻ (Bromide), and Rb⁺(Rubidium ion).
