Bell Ringer 11/5/14 1. How are the elements on the Periodic Table organized? 2. Pick one group of elements on the Periodic Table and describe two of its properties.
This family group has a full octet (8) in its outer shell and are not very reactive? Copyright © 2010 Ryan P. Murphy A- Halogens B- Alkali Metals C- Noble gases D- Transition Metals
The Periodic Table of the Elements is all of the following except? – A.) A chart of all the known elements. – B.) Is in order of decreasing atomic number and mass. – C.) A table that puts elements into groups with similar characteristics. – D.) Something that allows chemists to recognize trends over the whole array of elements. Copyright © 2010 Ryan P. Murphy
Please name A, B, C, and D? – And name the atom? Copyright © 2010 Ryan P. Murphy
The nucleus of the atom is… – A.) Very dense. – B.) Very, very, dense. – C.) Very, very, very dense. – D.) Very, very, very, very dense. – E.) Very, very, very, very, very, dense. Copyright © 2010 Ryan P. Murphy

Move Around The Room! Move to the correct Periodic Table Group on the wall after each question!
You need 18 index cards. 1. Cut the index cards in half 2. Using the atomic #, put the below information on each card for the first 36 elements on the periodic table. (Front of index card)(Back of index card) Atomic # Element NameChemical Symbol Atomic mass
Exit Ticket 1. How many electrons are in the outer shell of Group 2, the Alkaline Earth Metals?
