Rating Newest Oldest. Best Answer: Krypton has 8 valence electrons. It is a noble gas, meaning it has the maximum number of valence electrons its outer shell can hold.You know because it is in group 8A of the periodic table, therefore it has 8 valence electrons. The group number tells you how many electrons are in the valence shell.:).t is a noble gas, meaning it has the maximum number of valence electrons its outer shell can hold.
