WARM UP: + Write homework – leave it out to be stamped Update Table of Contents for today On page 9, number 1-10 leaving a few lines between each…then REVIEW YOUR NOTES FROM LAST CLASS! Date 9/19/2 Session # 4 Activity Page # Atomic Challenge Gallery Walk (written in notebook) 9 BrainPOP Quizzes 10 + Remember! We have learned there are 2 ways to represent a neutral atom of an element: Sodium + Lets try our math a different way today! Atomic # = __________ Atomic Mass = ________ # of Protons = _________ Element Name: ________ # of Neutrons = ________ Element Symbol: ______ # of Electrons = ________ + One More Time… Atomic # = __________ Atomic Mass = ________ # of Protons = _________ # of Neutrons = ________ Element Name: ________ # of Electrons = ________ Element Symbol: ______ + REVIEW: What happens when you mess with subatomic particles? What happens when you change the number of protons? What happens when you change the number of electrons? What happens when you change the number of neutrons? + REVIEW: IDENTITY If you add two protons to the element Zinc, which element will it become? If you take three protons away from Copper, which element will it become? + REVIEW: IONS If Beryllium loses 2 electrons, will it have a negative or positive charge? Will it be an anion or cation? If Chlorine gains 1 electron, will charge will it have a negative or positive charge? Will it be an anion or cation? + REVIEW: ISOTOPES If you have Carbon-12 and add one neutron to it then it becomes… If you have Sodium-22 and take three neutrons away from it then it becomes… + IN SUMMARY… PROTONS = IDENTITY ELECTRONS = ION (CHARGE) NEUTRON = ISOTOPE (MASS) + Ion Review & Quiz Atomic #: __________ Atomic Mass: _______ # of Protons: _______ # of Neutrons: ______ # of Electrons:______ Name:_________ Symbol:________ #1 Atomic #: __________ Atomic Mass: _______ # of Protons: _______ # of Neutrons: ______ # of Electrons:______ Name:_________ Symbol:________ #2 Atomic #: __________ Atomic Mass: _______ # of Protons: _______ # of Neutrons: ______ # of Electrons:______ Name:__________ Symbol:_________ #3 #4 Atoms of the same element with different numbers of neutrons are called ____________. #5 If an atom loses or gains an electron, it becomes an ____________. Gaining an electron results in a negative _________, losing an electron results in a positive _________ Atomic #: __________ Atomic Mass: _______ # of Protons: _______ # of Neutrons: ______ # of Electrons:______ Element:__________ Symbol:__________ #6 Atomic #: __________ Atomic Mass: _______ # of Protons: _______ # of Neutrons: ______ # of Electrons:______ Element:_________ Symbol:__________ #7 #8 Changing the number of protons results in a ________________________. For example: - one proton = ___________ + one proton = ____________ Atomic #: __________ Atomic Mass: _______ # of Protons: _______ # of Neutrons: ______ # of Electrons:______ Element:_________ Symbol:_________ #9 #10 1. Draw the Bohr diagrams for Beryllium (Be) and Argon (Ar) 2. Are they happy and stable? + Isotope Review & Quiz + CLASSWORK/HOMEWORK Create your own… “Atoms Family Album” • Fold the album together in a way that you would like, but it must have room for all 5 family members YOU MUST INCLUDE: • • • a representative drawing/printed picture and a description of the following family members: PROTON, NEUTRON, ELECTRON, ION, (both anion & cation must be represented) & ISOTOPE + Quiz Time! Close your notebook Open the textbook to page D-20 to use the Periodic Table…this is the ONLY thing your are allowed to use! When you are finished, please put your quiz in the basket and begin working on your Atoms Family Album!
