Answer:
Here is a summary of the information from the search results:
Covalent bond: a bond in which one or more pairs of electrons are shared by two atoms.
- Ionic bond: a bond in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other.
- Hydrogen bond: a weak bond in which a hydrogen atom in one molecule is attracted to an electronegative atom (usually nitrogen or oxygen) in the same or different molecule.
Based on the information from the search results, we can conclude that:
- Covalent bonding involves the sharing of electrons between two atom.
Ionic bonding involves the transfer of electrons from one atom to another, resulting in the formation of positively and negatively charged ions that attract each other.
Hydrogen bonding is a weak intermolecular force that occurs between a hydrogen atom in one molecule and an electronegative atom in another molecule.
