SPI 0807.9.1 Atoms Notes Science Tennessee SPI Objective: Recognize that all matter consists of atoms. Essential Learning Students will examine the basic structure of atoms and will learn to distinguish between things that are comprised of atoms and those that are not. Essential Question(s) What is the basic structure of atoms, and how can we distinguish between things made of atoms and things that are not?

Notes Science Tennessee SPI Objective: Atoms Notes Science Tennessee SPI Objective: Recognize that all matter consists of atoms. All matter is made up of atoms Matter is anything that has mass & takes up space (volume) Matter is anything that is solid, liquid, gas, or plasma These objects are made of matter. Therefore they are made of atoms. Bowling Ball (solid) Orange Juice (liquid) Oxygen (gas) The Sun (plasma)

Notes Science What do these 3 items have in common? SPI 0807.9.1 Atoms Notes Science Tennessee SPI Objective: Recognize that all matter consists of atoms. What do these 3 items have in common? They all have mass and take up space (volume) They are either solid, liquid, or gas So they are all made of matter which is made of atoms Rock Insect Flower

Things that are not made of matter Ask yourself if it is a solid, liquid, or gas Time Example: Time is not made of atoms Time is not a solid: You can not touch it Time is not a liquid: You can not drink it. Time is not a gas: You can not smell it. Solar Radiation Example: Energy is not made of atoms Energy is not a solid Energy is not a liquid Energy is not a gas Magnetic Force Example: Force is not made of atoms Force is not a solid Force is not a liquid Force is not a gas

Be 4 Legend 9.0 Notes Science SPI 0807.9.1 Atoms We once thought atoms were the smallest particles. We now know there are even smaller particles They are called sub-atomic particles (protons, neutrons, and electrons) Notice the sub-atomic particles in this beryllium atom It has 4 (blue) protons (So the atomic number is four) It also has 5 (green) neutrons and 4 (orange) electrons 4 Be Beryllium 9.0 Legend =protons =neutrons =electrons

Li 3 6.9 Notes Science SPI 0807.9.1 Atoms Atoms are made of three sub-atomic particles… …3 protons (the blue circles) (atomic number is 3) …4 neutrons (the green circles) …3 electrons (the orange circles) 3 Li Lithium 6.9 Here is a model of a lithium atom

Legend Notes Science SPI 0807.9.1 Atoms Protons: positive charge, found in the nucleus of atoms Note: In atoms the number of protons & electrons are the same Neutrons: no charge, also found in the nucleus of atoms Nucleus Legend =protons =neutrons =electrons

Legend Notes Science SPI 0807.9.1 Atoms Electrons are located in the electron cloud in areas called electron shells This atom has 2 electron shells. (see cloud in green area below) These can also be called electron energy levels or electron orbitals. The green area is the electron cloud area 1st Shell Legend =protons =neutrons =electrons Nucleus Nucleus 2nd Shell
