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.

Any element with an atomic number greater than 10 is capable of hypervalency. Electrons in the valence shell of these elements can be placed into hybridized d-orbitals during bonding if it is necessary to reduce the formal charge on the central atom of a molecule.he elements in period 3 and above have d orbitals available for bonding which makes the expansion of the octet more likely. period 2 elements do not, the 2d shell has only â¦ s and p orbitals.
