Detailed explanation-1: -Krypton has 8 valence electrons. Was this answer helpful?
Detailed explanation-2: -Krypton has 8 valence electrons.
Detailed explanation-3: -Since krypton is in the far right row of the periodic table, its outermost shell is full with eight electrons.
Detailed explanation-4: -Any element in group 18 has eight valence electrons (except for helium, which has a total of just two electrons). Examples include neon (Ne), argon (Ar), and krypton (Kr).
Detailed explanation-5: -The Group 8A elements have a full octet of eight valence electrons in their highest-energy orbitals (ns2np6), so these elements have very little tendency to gain or lose electrons to form ions, or share electrons with other elements in covalent bonds.
