How many electrons are in k
WebThat formula represents the maximum number of electrons per shell, NOT the actual number in any element's particular shells. Most notably, there is no element massive enough to have more than 32 electrons in any of its shells, even though, hypothetically, shells beginning with shell 5 could have more than that number of electrons.
