### Transcript

• 1. The parts of an Atom
• 2. The atomAn Atom: The most basic unit of matter.An atom has a dense nucleus and a cloud of negatively charged electrons around it. If matter is what everything is made of, and matter is made of atoms… Then, everything is really made of atoms!
• 3. An ElectronElectron: A subatomic particle with a negative electrical charge.An electron’s mass is so small that it is generally not even considered.
• 4. A NucleusNucleus: The dense center of an atom containing protons and neutrons. Nucleus
• 5. A ProtonA Proton: A subatomic particle within the nucleus of an atom that has a positive charge.
• 6. NeutronA Neutron: A subatomic particle within the nucleus of an atom that has a neutral charge.
• 7. Energy LevelThe energy level of an atom is as follows:2,8,8 The first shell has two electrons The second shell has 8 electrons The third shell has 8 electrons MEMORIZE: 2,8,8!!!!!!!!!!
• 8. Atomic NumberThe atomic number is the number mainly associated with the element and represents the number of protons present in the atom.
• 9. Mass NumberThe total number of protons and neutrons.The mass of an atom comes from the protons and neutrons. Therefore, the mass includes the masses of each added together. This number can be found Mass Number at the bottom, typically.
• 10. Atomic MassSub atomic particles are measured in AMU’s. AMU stands for Atomic Mass Unit.Every proton has a mass of 1 AMUEvery Neutron has a mass of 1 AMURemember, electrons don’t have a measureable mass.
• 11. ElementA pure chemical substance consisting of ONE type of atom.
