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.

Bromine (Br) has atomic number 35. it has 35 electrons, and has one electron less of that of Krypton. so the configuration of Bromine is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p5. as it regains stable configuration of Krypton by just capturing one electron, its valancy is 1. and thus is very electronagative and very reactive. it can form cobalant bond with another atom of bromine to form molecular bromine (Br2) liquid.
