1. Discuss the following with your table What is an element? What is the difference between and element and an atom? What is the difference between a compound and a mixture?

2. Find the definition of your word Give at least 2 examples Draw a picture that represents your word Assignments by stickers on your desk: Blue – element Green – mixture Yellow – compound Each table can use a tablet to look up information. There is also a computer in the back that may or may not work, and you are welcome to use your phones to look up information. As a table group, create one final slide that explains the difference between all 3 words AS WELL AS the definition and an example of an atom Use words, pictures, and COLOR

4. Protons Neutrons Electrons

5. Protons Positively charged (+1) Found in the nucleus Number determines the identity of the atom Mass of 1 AMU (atomic mass unit) Neutrons Electrons

6. Protons Neutrons Neutral charge Found in the nucleus Mass of 1 AMU Electrons

7. Protons Neutrons Electrons Negatively charged (-1) Found outside the nucleus Very small mass Can easily be transferred to other atoms

9. Element name

10. Element symbol

11. Atomic Number Tells you three things about the element: 1.Location on the periodic table 2.Number of protons 3.Number of electrons when neutral

12. Average Atomic Mass Average mass of ALL carbon atoms in AMU (atomic mass units) For an INDIVIDUAL atom: mass = protons + neutrons

13. Protons = atomic number Electrons = atomic number As long as the atom is neutral For now, assume everything is neutral Neutrons = atomic mass – atomic number
