Elements cont. Hydrogen is the simplest element It only has ____ proton and _____electron It is also the ______________________
Periodic Table Periodic Table: _______________________________________________________________________________________________________________________ The elements ________________________________________________________________________________________________________________________ The elements in the ____________________________________________________________________________________________________________________________________ The elements in the ________________________________________________________________________________________________________________________________________________
Families Each of the columns are a family (they all have names) _____________________________________based on their Valence # and characteristic properties There are 8 important families
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
Periodic Table cont. Staircase in the Table: the line that divides metals and non-metals Metals : to the left of the staircase Non-metals: to the right of the staircase Metalloids: on the staircase 6 total (in green in your textbook)
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 ___________________________________________________________________________________________________________________________
How to draw your Element By using the Atomic #, family/group and period you can draw your element Oxygen Atomic # = 8 Family = 6 Period = 2 8 electrons 6 electrons on the last ring 2 rings total
