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.

That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons. Electrons are arranged around atoms in a special way. If you need to know how the electrons are arranged around an atom, take a look at the 'How do I read an electron configuration table?' page.
