metallic, ionic, and covalent bonds
Metallic bonds bond identical atoms together if they are both metal atoms, but not if they are other identical atoms. For example, the bonds holding two chlorine atoms together to make Cl2 are not metallic bonds.
Atoms combine together to form molecules. In molecules the consitutent atoms are held together by attractive forces. This attractive force which binds the atoms in a molecules is called as bond.
These atoms form new substances where atoms are associated by chemical bonds.
covalent bonds
Sub atomic articles cannot make covalent bonds as atoms do.
In a chemical reaction, the bonds between the atoms of the reactants break, and new bonds are formed to make the products. The atoms do not change, they are just rearranged.
In the chemical bonds of its monomers.
Chemical bonds are formed by the sharing or donating of electrons. The electrons that atoms use to make chemical bonds are the outermost electrons, also known as valence electrons.
Bonds are attractions between atoms. They usually share electrons, or gain them, or lose them to make sure their layers have the full electrons that they need.
covalent bonds
Covalent bonds involve sharing of electrons.
Covalent bonds between carbon atoms; simple, double or triple.
