Essential LearningStudents will examine the basic structure of atomsand will learn to distinguish between things thatare comprised of atoms and those that are not.

Essential Question(s)What is the basic structure of atoms, and how canwe distinguish between things made of atoms and things that are not?

Notes

Tennessee SPI Objective:Recognize that all matter consists of atoms.

Science

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

Bowling Ball(solid)

Orange Juice(liquid)

The Sun(plasma)Oxygen

(gas)

These objects are made of matter. Therefore they are made 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 gasSo they are all made of matter which is made of atoms

Things that are not made of matterAsk yourself if it is a solid, liquid, or gas

Example: Force is not made of atoms

Example: Energy 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.

Example: Time is not made of atoms

Time

Solar Radiation

Magnetic Force

Energy is not a solid Energy is not a liquid Energy is not a gas

Force is not a solid Force is not a liquid Force is not a gas

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

Notes

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)

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)

Here is a model of a lithium atom

Protons: positive charge, found in the nucleus of atomsNote: In atoms the number of protons & electrons are the sameNeutrons: no charge, also found in the nucleus of atoms

Electrons are located in the electron cloud in areas called electron shells

This atom has 2 electron shells.

1st ShellThe green area is the electron cloud

areaNucleus

(see cloud in green area below) These can also be

called electron energy levels or electron orbitals.
