By the end of these lessons students will be able to:

• 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.

• Accurately identify molecules, elements, atoms, and compounds.

• 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.

Quick review with a little more detail…

• 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
