Periodic Table

100

What does the atomic number tell you?

The number of protons / electrons an element has

200

The Periodic Table is organized in many ways, what happens to the size of elements as you move right and down the table?

Elements get bigger as you move right/down the table. The element number increases

300

14.007 amu

400

Group 1-3 and 13-18 of the Periodic Table share the same trend. This trend is not included in the D-Block. What is it?

You can see how many Valence Electrons an element has if they are in Group 1-3, 13-18

500

Atoms

100

What particles make up the nucleus of an atom?

Protons and Neutrons

200

What are the charge of Electrons, Neutrons, Protons?

Electrons- Negative (-1)
Neutrons - Neutral ( 0 )
Protons - Positive (+1)

300

Carbon has 6 Protons, 6 Neutrons, and 6 Electrons. Draw a Bohr model of Carbon. 

Bohr models do not show protons/neutrons. The first ring has 2 electrons, the second ring has 4

400

Chlorine has 7 valence electrons. Draw a Lewis Dot Structure of Chlorine

"Cl" should be in the middle, with 7 electron "dots" around the element
