By the end of these lessons students will be able to:
Correctly locate, identify and describe the three subatomic particles of the atom.
2) Determine the number of neutrons, protons, electrons and element name when given the atomic number and atomic mass.
3) Describe the differences and similarities of isotopes and their more standard counterparts – and also explain how humans have used isotopes in dating things.
Name the two general types of chemical bonds and explain how the electron interaction works for both.
Step 1: Get into groups of at least 3 people
Step 1: Get into groups of at least 3 people
Step 2: Draw a picture of an atom (make sure each part is correctly proportioned to each other part)
Step 3: Make sure your picture includes the following: labeled parts (with an explanation of what each part does), specify the number of each part in your atom, and also name your element.

Nucleus: The center area of the atom containing just about all of the atomic mass, which is found within the neutrons and protons that make up this location.
Protons: Positively charges subatomic particles found in the nucleus. The number of these particles determines what element the atom is.
Nucleus: A non-charged subatomic particle also found in the nucleus, necessary for the stability of the nucleus.
Electron: A negatively charged subatomic particle found in constant motion around (but distant from) the nucleus. Equal in number to the protons in standard atoms.
How would you define ‘Element’?
How would you define ‘Element’?
Atom: Smallest unit of an element.
Atom: Smallest unit of an element.
Element: A pure substance that consists entirely of one type of atom.
Compound: A substance formed by the chemical combination of two or more elements in definite proportions.
Molecule: Two or more atoms joined together. A compound is a molecule, but a molecule does not have to be a compound. i.e. O2 and H2O
