Monday, March 9 Pick up a Periodic Table Packet and put your name on it. DO NOT LOSE THIS – IT IS A PROJECT GRADE!!! Read on pages 3-4 in the packet, the readings called “ A Brief History of the Periodic Table ” and “ The Modern Periodic Table”. Think about how the Periodic Table was discovered and developed based on the properties of elements and atoms. Copy the atom notes on the board onto the back of your packet. Leave space for additional video notes.
Atom Video As you watch the Brainpop clip, reflect on: How the atomic model changed over time Who the key figures were The model we use today
Periodic Table Videos Who discovered the Periodic Table? How does it classify/organize elements? http://www.pbslearningmedia.org/asset/nvhe_vid_periodic/ http://www.pbslearningmedia.org/asset/nvhe_vid_periodic/
Arrangement of Elements Elements are organized according to their properties. You can predict an element’s properties based on its location on the periodic table.
LEFT SIDE : shiny, good conductors, bendable RIGHT SIDE : dull, poor conductors, brittle ZIG ZAG LINE : have some properties of metals and some of nonmetals
Arrangement of Elements 7 PERIODS horizontal rows Element properties in each period change in a pattern (metals, metalloids, nonmetals) 18 GROUPS vertical columns Elements in each group have similar characteristics/properties.
Atomic Structure The center of an atom nucleus. Contains protons [+] and neutrons [no charge/neutral]. Protons and neutrons have about the same atomic mass. Most of an atom’s mass comes from its nucleus. Electrons [-] move around the nucleus in a negatively charged cloud. Mostly empty space Electrons have a very small mass
To Do Follow the instructions on Page 1 of your packet for coloring and labeling your Periodic Table Color lightly so you can still see all information *Do not lose this packet – it is a project grade! You must bring it every day to school with you.
