It depends on the element in question. The outer most shell of electrons will hold the remainder of the electrons after all inward shells are filled. The first shell will only hold up to 2 electrons. After each shell holds up to 8 electrons (if the atomic number is <20).
Sulphur has 6 electrons in its outermost shell.
thallium has 3 electrons in outermost shell.
It has 5 electrons in its outermost shell.
There are 2 electrons in the outermost shell of strontium. Strontium has an electron configuration of [Kr] 5s^2, indicating that it has two electrons in its outermost shell.
There are 2 electrons on the outermost shell of calcium.
6 electrons.
