Matter and Atomic Theory

Today we started talking about matter and atomic theory. We filled out a chart for the first twenty elements it should look something like this. 

Name	Chemical Symbol	Number of protons	Number of neutrons	Number of electrons	Atomic   Number	Mass Number	Number of valence electrons	Lewis Dot Diagram
Hydrogen
Helium
Lithium
Beryllium
Boron
Carbon
Nitrogen
Oxygen
Fluorine
Neon
Sodium
Magnesium
Aluminum
Silicon
Phosphorous
Sulfur
Chlorine
Argon
Potassium
Calcium

I've said this a million times and will continue to say it - if you have any questions during the lecture or while we are completing classwork, please ask me!!! If you do not understand one part or even the whole of the assignment please ask me before turning it in.

The vocabulary for this section is as follows:

atom, atomic mass, atomic number, chemical properties, chemical symbol, electron, electron cloud, element, ion, isotope, matter, mass number, neutron, nucleus, physical properties, proton, quark, radioactivity, valence electrons
