Mixture Separation Mechanism

Physical Properties that allow separation

1. Sand and Iron Filings

2. Salad

3. Salt and Water

4. Muddy Water

5. Dust in Air

What is a Solution?

1. A homogenous mixture– appears to be a single substance

2. Solvent– the largest quantity in the mixture

3. Solute– smallest amount of a substance in a mixture

• WATER is the UNIVERSAL SOLVENT

P.T. connection to Atomic Structure

1. Row # = # of shells in atomic Bohr structure (1-3)

2. # of Elements in each row = the maximum # of electrons that shell can hold.

3. Atomic Number = # of protons (determines identity of ATOM)

4. Atomic Mass = # of protons + neutrons

Using your NOTES: 1.Complete the vocabulary on your own.2.MINIMUM of 2 bullets of info for each word and COLORED picture.

Open your Textbook to the Periodic Table.
