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.

The shell closest to the nucleus, the K shell, has a capacity for two electrons. The next shell, L, has a capacity for eight, and the third shell, M, holds up to 18. The atomic number for nitrogen is seven, which means it has seven protons and seven electrons in the atom. Two electrons are in the innermost K shell. The remaining five electrons go in the nitrogen atom's valence shell. Learn more about Chemistry
