Question

Define a chemicle bond.

Describe the type of bonding that exists between the atoms in hydrogen molecule, H2

Describe the type of bonding that exists between the atoms in the hydrogen Floride molecule, HF

Answer 1

H2- non-polar covalent bonding ;equal sharing of bonding electrons - the difference in electronegativity is zero. ( note: they are the same atoms)

HF polar covalent bonding ;unequal sharing of electrons because of the considerable difference in the electronegativities of H an F(note: F is the most electronegative element)

By the way, chemical bond is refers to the electrostatic and physical forces holding atoms together to form molecules and solids. Bonds can be ionic, covalent or metallic
