Elements in the first row of the periodic table never have expanded octets. Because sulfur is far less electronegative than oxygen.
Which Elements Can Have Expanded Octets. Typically, the atoms with the greatest electronegativity have complete octets, and those with the lowest electronegativity have the unpaired electron. Which elements can have expanded octets? Elements in period 3 and beyond. Which elements cannot have expanded octets?

Elements in the third row of the periodic table and beyond often exhibit expanded octets. An expanded octet cannot occur with atoms less than atomic number 10 (neon) because there are no d orbitals. Sulfur and phosphorus are common examples of this behavior. Notice that “expanded octets” only occur in compounds in which the central atom has low electronegativity relative to the ligands.
In the case of octet expansion, the rule is broken.
Which elements cannot have expanded octets? The university of alabama 01:22. • there is an odd number of electrons, like in radicals • there are less than 8 electrons or incomplete octet • there are more than 8 electrons or expanded octet. Recall that the octet rule states that an element is surrounded by eight electrons in the lewis structure. Periodic table can or cannot expand the oct it. Typically, the atoms with the greatest electronegativity have complete octets, and those with the lowest electronegativity have the unpaired electron.

Elements in the third row of the periodic table and beyond often exhibit expanded octets. As per octet rule, atoms bond in a way that they have eight electrons in their valence shell. The elements that typically have less than an octet are hydrogen, helium, lithium, and beryllium.

Recall that the octet rule states that an element is surrounded by eight electrons in the lewis structure. 1) odd octets, seen in electron species, molecules, or ions with an odd number of valence electrons (no). Main group elements that form more bonds than would be predicted by the octet rule are called hypervalent compounds, and have what is known as an ‘expanded octet,’ meaning that there are more than eight electrons around one atom.

Notice that “expanded octets” only occur in compounds in which the central atom has low electronegativity relative to the ligands. Elements in the third row of the periodic table and beyond often exhibit expanded octets. Atoms in these periods may follow the octet rule, but there are conditions where they can expand their valence shells to accommodate more than eight electrons.
