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.

A valence electron is an electron in the outermost electron shell of a representative element or noble gas element. The number of valence electrons in a representative element can be determined by its electronic configuration. For elements in Groups IIIA through VIIIA the outermost s and p electrons in the highest energy shell are valence electrons. 2  For transition elements the valence electrons are those in the outermost s sub-shell and in the d sub-shell of the next to outermost energy shell.
