chemical bonds
Chemical Bonds
Hydrogen bonds are weak bonds that are not strong enough to hold atoms together to form molecules but are strong enough to form bonds within and around large molecules.
Yes sometimes, that is how covalent bonds are formed.
Atoms within molecules are bound by bonds of different types, but nothing physically attaches them, technically. Forces, almost all magnetic, help pull atoms together, though the strength of this force has to be stronger than the heat movement in order to actually hold these atoms together.
Molecules are two or more atoms held together by a covalent bond. This is a very strong bond as it is held together by strong electrostatic charges. All covalent molecules (apart from those held together in a covalent lattice such as Diamond) are bonded to other molecules by Van der Waal forces. Its is these intermolecular bonds that control boiling and melting points. Van der Waals are (in this case) the attractive force between molecules, they are temporary bonds between temporary dipoles and as electrons orbit the nuclei of atoms the position changes. This temporary dipole induces other molecules to form induced dipoles. Strength varies due to shape of molecule (the more "oblong" the greater the strength of the bond) and by size (the greater the size the greater the strength of the bond.)
It is the electromagnetic force that holds electrons and protons together in atoms, and which hold atoms together to make molecules.
Chemical Bonds
These bonds are ionic or covalent.
Chemical Bonds
Hold polar molecules together
In Nature, molecules are two or more different element atoms that are joined together using chemical bonds (the forces that hold atoms together). A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

The most common bonds are ionic and covalent.
Covalent bonds hold atoms together. Ionic bonds hold ions together
If Coulomb's force is gone , the material structure of the Cosmos would be gone. Coulomb's force hold atoms together and molecules together and matter together.
Intermolecular force holds large numbers of different molecules together.
