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 valence electrons are found on the valence shell, the outermost  shell of an atom.    By using the periodic table and the group numbers, one can find the  number â¦ of valence electrons for elements in groups (vertical  columns) 1-2 and 13-18.wo, two valence electron Oxygen has two valence electrons since it must gain two in order to obtain 8 electrons in its outermost energy level. However, the number of valence â¦ electrons is six--not two. The valence and valence electrons are only the same for metals in Groups 1, 2, and 3.
