Solids, liquids, gases - all matter - are made up of atoms (or other things, like molecules, that are made from atoms)! ELEMENTS are the kinds of atoms that we can have. Carbon is an element, hydrogen is an element, and so is oxygen. Atoms can join together - they form bonds together - to make MOLECULES.
Similarly, you may ask, how does a molecule work?
Protons, neutrons, and electrons can then organize to form atoms. Atoms are then used to create the molecules around us. Smaller molecules can work together and build macromolecules.
How molecules are held together?
An example of a molecule held together by covalent bonds is . Polar molecules have a positive region – in water it is the two hydrogen atoms. If the atoms in a water molecule are held together by covalent bonds, what type of bond holds multiple molecules together?
