Note that no atom in our hypothetical element has a mass of 10.5 u; rather, that is the average mass of the atoms, weighted by their percent occurrence. This example is similar to a real element. Boron exists as about 20% boron-10 (five protons and five neutrons in the nuclei) and about 80% boron-11 (five protons and six neutrons in the nuclei).
The type of bond that is most likely to occur between two atoms can be predicted on the basis of the location of the elements in the periodic table, and to some extent the properties of the substances so formed can be related to the type of bonding. A key concept in a discussion of chemical bonding is that of the molecule.

In this lesson, students gain an understanding of what elements, molecules, compounds and mixtures look like at the molecular level. Students use marshmallows to represent atoms and toothpicks to represent bonds. The purpose of the lesson is not for them to learn how to bond, but to notice what the particles might look like in each type of matter.
