  1. Matter

  2. Families of the Periodic Table

  3. What is Matter? • The table that you just bumped into is made of solid matter. Things that take up space and have mass are called matter. You interact with matter everyday and everywhere you go. Now, take a deep breath and blow up this balloon. You just filled the balloon with matter. Gas in the balloon is matter. Liquids that you drink every day are also matter.

  4. What Does Mass Mean? • We use the word mass to talk about how much matter there is in something. (Matter is anything you can touch physically.) Often, the amount of mass something has is related to its size, but not always. A balloon blown up bigger than your head will still have less matter inside it than your head (for most people, anyhow) and therefore less mass.

  5. What’s the difference between mass and weight? The difference between mass and weight is that weight is determined by how much something is pulled by gravity.

  6. Mass vs. Weight If we are comparing two different things to each other on Earth, they are pulled the same by gravity and so the one with more mass weighs more. But in space, where the pull of gravity is very small, something can have almost no weight. It still has matter in it, though, so it still has mass.

  7. Lewis Structures • What is it? • A Lewis Dot Structure is a symbolic description of the distribution of valence electrons in a molecule. • How do I create one? • http://www.youtube.com/watch?v=y6QZRBIO0-o Step 1: Draw out the Chemical Symbol Step 2: Find the total number of valence electrons. Step 3: Draw the Valence electrons around your symbol

  8. Examples of Lewis Structures

  9. Valence Electrons??? • an electron in the outer shell of an atom which can combine with other atoms to form molecules. • Molecules??? • http://app.discoveryeducation.com/player/?assetGuid=74d64d19-4991-405e-ad4f-e91d86565610&fromMyDe=0&isPrinterFriendly=0&provider=&isLessonFromHealth=0&productcode=DETB&isAssigned=false&includeHeader=YES&homeworkGuid=
