Acovalent bondis formed by the equal sharing of electrons from both participating atoms. The pair of electrons participating in this type of bonding is called a shared pair or bonding pair. Covalent bonds are also called molecular bonds. Sharing of bonding pairs will ensure that the atoms achiev...

Explain why CH4 is one of the most common molecules found in nature. Are the bonds between the atoms ionic or covalent? Why can a hydrogen atom form a covalent bond without fulfilling the octet rule? How can electronegativity cause a covalent bond to be polar?
Molecules with three or more atoms have two or more bonds. The sum of all bond energies in such a molecule is equal to the standard enthalpy change for the endothermic reaction that breaks all the bonds in the molecule. For example, the sum of the four C–H bond energies in CH4, 1660...

nonpolar bonding only occurs when the particles are identical to each other (e.g., H2 gas). Still, chemists consider any bond between atoms with a difference in electronegativity less than 0.4 to be a nonpolar covalent bond. Carbon dioxide (CO2) including methane (CH4) are nonpolar molecules...
A polar covalent bond is different from a nonpolar covalent bond because the atoms in a polar covalent bond do not share electrons equally. During a...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your t...
