Expanded octet examples
WebNumerous compounds of these elements have more than eight valence electrons around the central atom. This is termed as the expanded octet. Some examples of such compounds are: PF5, SF6, H2SO4 and a number of coordination compounds. Learn more about the advances in chemical bonding with the expert faculty at BYJU’S. WebAug 22, 2024 · For example, the Lewis structure of SF 6 can be redrawn with two ionic S-F bonds and four covalent S-F bonds as shown in Figure \(\PageIndex{1}\). In this picture the central S atom has six F atoms coordinated, but only shares four bonding pairs of …

WebApr 8, 2024 · Octet Rule Examples A few examples which follow the octet rule are : CO2, NaCl, MgO 1.CO2 Carbon contains four electrons in its outermost shell. Also, carbon should have four electrons to complete its octet when it is combined with two molecules of oxygen. Here each carbon atom requires two electrons to complete its octet. WebExpanded octet occurs when an atom is able to have more than 8 valence electrons. For example, in SO₃, the sulfur atom forms 6 covalent bonds, hence it has 12 valence electrons. Expansion of octet is possible only from Period 3 elements onwards, due to the presence of low-lying empty d orbitals that can accommodate the extra electrons.
