Atomic Number – Number of Protons - This is how elements are arranged on the periodic table
Neutral Atom –Protons = the number of Electrons
Atomic Mass Number – Number of Protons + Neutrons - The total mass of the nucleus
Connection to the Periodic Table of Elements (p. 20 D)

CCarbon12.001
Atomic Number = # of Protons / Electrons
Symbol = 1st letter always capital
Atomic Mass = Protons + Neutrons

Homework:1. Finish Periodic Table Worksheet
- Parts 1 and 2 ONLY
Warm up:
Finish Periodic Table worksheetIntroduction, Organization and History of the
Periodic Table
1. Determine what element this Bohr model is representing.
2. How did you come to this conclusion?
3. Draw a Bohr model for Helium and Neon – can you make any observations that make these two alike in any way?
4. Make a t-chart and compare and contrast mixtures and pure substances.

Matter• Has mass or weight
• Takes up space (volume)•Cannot occupy the same space as other matter at the
same time
Pure Substances• Has the same composition
throughout
• Can Occur Naturally
Mixtures• Formed when two or more substances are
physically combined• Parts can be physically separated
• Substances in a mixture retain their original properties
Element• Cannot be broken down into simper substances
Compound•Chemical combination
of two or more different elements
• Cannot be physically separated
•Properties are entirely different properties of
each element alone
Homogeneous• Parts of the
mixture are evenly distributed
Heterogeneous• Parts of the mixture are not
evenly distributed

Properties of ….Metals Metalloids
• Most are solids• Can be shaped &
pulled into wires• Shiny / lustrous• Good conductors
of electricity/heat• Tend to lose
electrons in chemical reactions
• Most are Solids• Can be shiny or
dull• Can be shaped
& pulled into wires
• Conducts better than nonmetals but not as well as metals
•Most are gases•Solid non-metals are brittle•Not shiny, but dull•Poor conductors of electricity and heat•Tend to gain electrons in chemical reactions
Non-metals

History of the Periodic Table
Dimitri Mendeleev (1834 – 1907) • Siberian• Founded the periodic table (1869)• Organized by Atomic Mass and
properties• Could predict where new elements
would go on the table
Henry Moseley (1887-1915)• Studied elements using x-rays• Was able to slightly reposition the
periodic table because he could see protons
• Killed in WWI at age of 28• Britain made a policy that restricts
scientists from fighting in wars
