The Periodic Table Elements RULE!
Remember... Matter: Anything that has a mass and takes up space
Matter is composed of: Elements!!!!! Elements
Element Material that cannot be broken down into new material that is stable or more simple through chemical reactions. Has a specific set of properties Hydrogen, Oxygen, Gold, Neon elements exist 94 of them occur naturally
Atom The smallest amount of an element (or substance) that still has all of the properties of the element. Cut a piece of aluminum...how many cuts can you make and still have Al?
Gold...As an Example atoms!!!!
What does an element look like? Made of Protons, Electrons and Neutrons
That is DRAWN MENDELEEV! He Came up with a way to organize the elements
The Periodic Table A table organized by similarities and differences among elements
Periods Elements in the same period have the same number of atomic orbitals (electron cloud)
How many shells should Li have? Guess...
Good!
Groups The Columns in the Periodic Table Number of electrons in outer shell Transition metals are drawn Group 1 has one electron in outer shell How many in Boron?
Boron is NOT boring
