The Atom

100

This is the positive charged part of the atom

What is the Proton?

200

This is the Negative charged part of the atom.

What is the Electron?

300

This is the natural part of the atom.

What is the neutron?

400

In the plumb pudding model of the atom, a circle is drawn representing the atom. An electron is represented by a dot within the circle. This represents the proton of the atom. 

What is the empty space within the circle? 

500

This device was used by JJ Thompson to prove that the electron was negatively charged. 

What is the Cathode Ray Tube?

Moving Electrons

100

In the sticky tape lab, this piece of tape carried the positive charge. 

What is the Top Tape?

200

When paper is held close to the positive tape strip, how do the electrons move? (Draw it out)

They stay within their own atoms, but all move to the side of the atom near the tape. 

300

When a positive tape strip is brought near a metal, how to the electrons move within the metal? (Draw it out).

Metals can transfer their electrons. Most of them will end up in the atoms closes to the the tape, and the atoms further away from the tape will have less electrons. 

400

This type of material is able to move electrons. 

What are metals? 

500

When we constructed circuits using a battery, light bulbs, and wires; this material let electrons flow and made the light bulb light up. 

What is (anything metal)?

Ionic Bonds

100

Ionic Bonds are made up of these two types of elements.

What are metals and non metals?

200

This is an atom that carries a charge. 

What is an Ion?

300

Dry Baking soda is an ionic compound (NaHCO3). Can it conduct electricity?

NO. It must be added to water and DISSOCIATED before it moves electrons. (Na+) and (HCO3-) ions floating in the water. 

400

KCl is an ionic compound. If the solid powder is added to water, will the new solution conduct electricity?

YES. The water will allow the compound to DISSOCIATE leaving (K+) and Cl- Ions. 

500

This formula unit forms a crystal lattice structure and arranges itself so that the negative atoms are surrounded by positive atoms. 

What are ions?

What is LiCl

200

Write the formula of Mg2+    and     Br–

What is MgBr2

300

What is the Formula for Pb2+    and    N3–

What is Pb3N2?

400

Write the formula for: Ca2+    and    SO42–

What is CaSO4?

500

Write the formula for NH4+ and OH–

What is NH4OH? 

Ionic Naming

100

Write the name of Li2O

What is Lithium Oxide.

200

Write the name of CaS.

What is Calcium Sulfide?

300

Write the name of FeCl2

What is Iorn II Chloride?

400

What is the name of Be(NO3)2.

What is Beryllium Nitrate?

500

Write the name of CuSO4

What is Copper II Sulfate?
