Use this investigation of the first 20 elements of the Periodic Table to illustrate the core concepts of atomic theory. This selection of magnetic element cards will stick to the black or white board in a classroom or office, and are designed to minimize the extra information given on more advanced periodic tables while focusing on essential points. This allows students to become active learners as they discover the concepts and trends as they sequentially build the table. The cards can be used to illustrate several major concepts including Families & Periods, Atomic Number & Mass, Electron Shells & Valency, and Isotopes. The set includes elements 1-20 plus: Hydride(H-), 14 additional elements (4 x H, 3 x O, 2 x CL, 1 x F, 2 x Na, 2 x K). 3Mg Isotopes, and Au & Pb. Teacher's notes also included.
