Draw the Bohr model for helium (there are two neutrons in helium).. Today’s Objectives. SWBAT explain that a ‘chemical formula’ describes the combination of two or more elements.. For Example: If you have a piece of gold and cut it into smaller and . smaller pieces, . you would eventually reach a point where you couldn’t cut the gold up any smaller. That smallest piece would be an atom of gold.. They can be joined together by . chemical bonds. From last lesson:. Atoms can have different numbers of protons, neutrons and electrons.. There are 118 different types of atoms.. They can be found on the periodic table of elements..
