WebFor example, each atom of a group 14 element has four electrons in its outermost shell and therefore requires four more electrons to reach an octet. These four electrons can be gained by forming four covalent bonds, as illustrated here for carbon in CCl 4 (carbon tetrachloride) and silicon in SiH 4 (silane). WebFluorine is a second period element which can only contain a maximum of 8 valence electrons. Xenon meanwhile can have an expanded octet and can hold more than 8 electrons. Basically any of the fluorine atoms wouldn't be able to hold onto an extra 2 electrons which only leaves the central xenon atom with the ability to. Hope that helps. cancer survivor face mask

Sulfur can have an expanded octet because it is in Row 3 of the periodic table, meaning that the quantum number n is equal to 3. When n=3, l can be 0, 1, or 2 according to the rules for quantum numbers. This means that elements in Row 3 have the S, P, and D subshells available to them to hold electrons.

WebJul 4, 2024 · Thus by using an expanded octet, a +2 formal charge on S can be eliminated. Less Than an Octet of Electrons Molecules with atoms that possess less than an octet of electrons generally contain the lighter s - and p -block elements, especially beryllium, typically with just four electrons around the central atom, and boron, typically with six.

WebShared pairs of electrons are drawn as lines between atoms, while lone pairs of electrons are drawn as dots next to atoms. When constructing a Lewis diagram, keep in mind the octet rule, which refers to the tendency of atoms to gain, lose, or share electrons until they are surrounded by eight valence electrons (an octet).
