Webbför 2 dagar sedan · 5 Properties of small molecules and polymers A substance with small molecules has strong covalent bonds that hold the atoms together in its molecules. … WebbImage of a methane molecule, showing its tetrahedral shape and the bond angle of 109.5 degrees for each H-C-H unit. Covalent bonding occurs in most non-metal elements, and in compounds formed between non-metals. Water is an example of a polar molecule; the oxygen end has a slight negative charge whereas the hydrogen ends are slightly positive.
