Why is xef2 linear

So lets now understand all the properties in detail. The Lewis structure of a given chemical compound is crucial for knowing all the physical properties and chemical properties. It is a pictorial representation of all the electrons participating in forming bonds. This structure helps in understanding the charges on the molecules of the compound.

The electrons that participate in bond formation, as well as the ones that do not participate, are collectively known as valence electrons. Electrons that take part in forming bonds are called bonding pairs of electrons. The ones that do not participate in bond formation are called lone pair of electrons. For distinguishing between the different types of electrons, both bonding and lone pairs of electrons are represented differently. The bond formation in the compound are represented as straight lines and the lone pairs are depicted as dots.

Lewis structure is based on the octet rule. This rule states that every molecule should have eight electrons in its outer shell of an atom to be stable. If there are more electrons than it, then that compound donates the electron. Whereas if there are less than eight electrons, the compound accepts the electrons from the other molecule to be stable.

So for this compound XeF2, there is one molecule of Xenon and two molecules of Fluorine. A single molecule of Xenon has eight electrons, and a Fluorine molecule has seven valence electrons. Hybridization of a given molecule is vital to understand the geometry of the molecule.

During bond formation, two or more orbitals with different energy levels combine and make hybrid orbitals. In XeF2, the outer shell of Xenon has eight electrons out of which two electrons participate in bond formation. The ground state of the Xenon has 8 electrons arranged in s2 p6 orbitals. Whereas in XeF2, the Xe molecule has an excited state.
