Element Chart

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

Calcium

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
