  1. Elements Pg 204-208

  2. Elements • Element: __________________________________________________________________________ • The number of __________is something unique and therefore a characteristic property • The number of ___________can differ for each element • The number of _____________also differ from each element

  3. Elements cont. • Hydrogen is the simplest element • It only has ____ proton and _____electron • It is also the ______________________

  4. Periodic Table • Periodic Table: _______________________________________________________________________________________________________________________ • The elements ________________________________________________________________________________________________________________________ • The elements in the ____________________________________________________________________________________________________________________________________ • The elements in the ________________________________________________________________________________________________________________________________________________

  5. Families • Each of the columns are a family (they all have names) • _____________________________________based on their Valence # and characteristic properties • There are 8 important families

  6. Periodic Table cont. • Elements can be found in all three states in the periodic table • __________________ • __________________ • __________________ • Many periodic tables use colour coding to help you see the difference • In your textbook Solid = black, liquid = blue, gas = red

  8. Periodic Table cont. • __________________________ • Atomic number (equal to the # of protons and electrons) • Chemical symbol • Name of element • You will need to know the first 20 elements plus: • Fe, Ni, Cu, Br, Ag, Sn, I, Au, Hg, U • ___________________________________________________________________________________________________________________________

  9. How to draw your Element • By using the Atomic #, family/groupand period you can draw your element • Oxygen • Atomic # = 8 • Family = 6 • Period = 2 • 8 electrons • 6 electrons on the last ring • 2 rings total
