According to the Oxford Dictionary, Covalent: Co/va/lent - Adjective, in Chemistry, Relating to or denoting chemical bonds formed by the sharing of electrons between atoms. Often contrasted with ionic.
Yes. By definition the bonds in any molecule are covalent
A single bond has - by definition, only one covalent bond.
water ammonia
The electrons in a polar covalent bond are never shared equally between atoms. That is part of the definition of a polar covalent bond. The bonds, regarded abstractly, are always shared between atoms, because that is part of the definition of a covalent bond.
By definition, any covalent chemical is a compound. Formic acid is a covalent chemical (specifically, a monoprotic organic acid CHOOH).
A bond in which electrons are unevenly shared between atoms
Pauling's definition of electronegativity Electronegativity is defined as the attracted force which an atom, bonded by a covalent bond, exerts on the bonded pair of electron responsible for the covalent bonding.
A type of chemical bond where two atoms share a pair of electrons with each other.
By definition, a covalent bond is a type of chemical bond characterized by the sharing of a pair of electrons between two atoms. If it's only one pair of electrons being shared, then it would be a single covalent bond, two pairs of electrons being shared is a double covalent bond, and three pairs of electrons shared would be a triple covalent bond.
Sorry that definition is inadequate as it could just as easily describe a covalent bond.
Because there are bonds there must by definition be more than 1 atom and hence a molecule.
