Question

Determine the number of bonding electrons and the number of nonbonding electrons in the structure of . ( OF2) AND (SI2)

Enter the number of bonding electrons followed by the number of nonbonding electrons in the dot structure of this molecule separated by a comma (e.g., 1,2).

Answer 1

Concepts and reason

• Lewis structures are the diagrams, which represent the chemical bonding between atoms of molecules and a lone pair of electrons that may exist in the molecule.

• It is also called as dot structures that represent lone pair and bond pair of electrons in the molecule.

• Lewis structures are used to draw covalently bonded molecule as well as coordination compounds.

• Bonding electrons are the electrons that participate in the bond formation. Nonbonding electrons are the electrons which do not participate in the bond formation.

Fundamentals

• Lewis structure represents the bonding and lone pair of electrons in the molecule.

• Valence electrons are the electrons present in the outermost shell of an atom.

• Dots are used to represent the electron position around the atoms; lines or dot pairs are used to represent covalent bonds between atoms.

• The Lewis structure is based on the concept of octet rule. So, the electrons shared in each atom should have at least 8 electrons in its outer shell.

• Bonding electrons are the electrons used for the bond formation.

Four out of the sixteen electrons are used as bonding electrons.

Therefore, number of bonding electrons in is four.

Number of nonbonding electron is 16.

Four out of the sixteen electrons are used as bonding electrons.

Therefore, number of bonding electrons in is four.

Number of nonbonding electron is 16.
