Hydrogen bonding is really not bonding, but only a polar interaction.
H2 [diatomic hydrogen] is an elemental bond in which gas atoms can cohabit.
The smallest unit of a pure substance that consists of two or more atoms held together by a chemical bond is a molecule.
No NaCl has nearly pure ionic bond
This the metallic bond.
No chemical bond, but a metallic bond.
All chemicals are held by chemical bond
Any chemical may be pure or impure.
The chemical bond of carbohydrates is called glycosidic bond.
it would be "pure" covalent bond. it is pure because the difference in electronegitivity is 0, resulting in a perfectly covalent bond.
Pure iodine (not in a compound) will bond with itself and will form I2. This is how it will almost always be found on its own.
Yes, it is a form of chemical bond. Other chemical bonds include ionic and metallic bond.
Any atom that hasn't undergone chemical bond.
The energy of chemical bond depends on the type of this bond: hundreds of kJ/mol.
