1 Early work #5: Draw your best diagram of what you think is an atom. (Just try!)

2 Some people draw an atom like this

3 Atom showing charges

4 Atomic Structure

5 What are the 3 major parts of an atom?

6 Proton Neutron Electron

7 Describe Proton

8 Protons Write this down under the Proton flap. Much larger/heavier than electrons Protons have a positive charge (+) Located in the nucleus (middle) of the atom

9 Describe Neutron

10 Neutrons Write this down under the Neutron flap. Large and heavy like protons Neutrons have no electrical charge Located in the nucleus of the atom

11 Describe Electron

12 Electron Write this down under the Electron flap. Tiny, very light particles Have a negative electrical charge (-) Move around the outside of nucleus in very specific energy shells

13 Describe Nucleus

14 Nucleus Write this down under the Nucleus flap. Nucleus is central part of atom. Composed of protons and neutrons. Nucleus contains most of an atom's mass.

15 Sooner or later every one of us breathes an atom that has been breathed before by anyone you can think of who has lived before us- Michelangelo or George Washington or Moses. Jacob Bronowski

16 Element Key Write this down inside the foldable. Take notes as directed. 6 C Carbon 12.0

17 The innermost shell closest to the nucleus can only contain how many electrons?

18 The innermost shell can only contain how many electrons? Models of an atom pictures electrons moving around the nucleus in a region called an electron cloud. The first energy shell contains TWO electrons. That’s it! For more information, click here:

19 How many electrons can the second energy level contain?

20 It can contain up to 8 electrons.

21 Describe Isotope Atoms that have the same number of protons but different numbers of neutrons

22 Describe Isotope Example:

23 Matter & The Atom

24 What is matter? The term matter describes all of the physical substances around us: your table, your body, a pencil, water, and so forth

25 Matter Anything that has mass and takes up space (has volume) Made up of different kinds of atoms

26 Matter Includes all things that can be seen, tasted, smelled, or touched Does not include heat, sound, or light

27 What is matter made of? Matter is made of atoms

28 Why use models? Models are often used for things that are too small or too large to be observed or that are too difficult to be understood easily

29 Models In the case of atoms, scientists use large models to explain something that is very small Models of the atom were used to explain data or facts that were gathered experimentally. So, these models are also theories
