Which element can accommodate more than eight electrons in its valence shell? Sulfur Electrons that just come and go - they don't stay with the atom. How did I know this? Example 1: A fluorine atom can get a full valence shell by either gaining one more electron, or by losing seven electrons.The former requires the transfer of less electrons, so the fluorine atom will try to gain one electron first. While inner electrons (those not in the valence shell) typically don't participate in chemical bonding and reactions, valence electrons can be gained, lost, or shared to form chemical bonds. So in addition to being octet, sulfur can expand octet to have 10 or 12 electrons. Sulfur has one more electron pair in its 3s subshell so it can undergo excitation one more time and place the electron in another empty 3d orbital. A fluoride ion has the same electronic structure as a neon atom (Ne). Hereof, how many electrons are in the valence shell of sulfur? For every Group 17 elements,it's valence shell contains 7 electrons. Iodine,with an atomic number of 53,is just an electron short to get itself satisfied with a noble gas configuration,like any other halogen.
