Making Ionic Compounds

Mariah Herrera, Callie Shelton, Kristina Brennan

Mr. Mclnroe
Hypothesis: The magnesium will not remain ionic after the reaction.

Purpose: The purpose of the experiment is to observe the evidence of a chemical reaction, acquire and analyze information that will characterize if the compound has an ionic bond, and to classify the products as ionic or not ionic.

-Magnesium ribbon
-Ring stand and ring
-Clay triangle
-Laboratory burner
-Stirring rod
-Crucible tongs
-Centigram balance
-100-mL beaker
-Distilled water
-Conductivity tester

Read the procedure. Identify the variables. The variables are the amount of magnesium ribbon and the amount of distilled water.
Write the electron configuration of the magnesium atom. 1s^2 2s^2 2p^6 3s^2
Based on this configuration, magnesium will lose electrons to become ionic.
Electron configuration of magnesium ion. Mg^2 + 1s^2 2s^2 2p^6
The magnesium ion has an electron configuration that of the neon noble gas.
Repeat question 2 for oxygen and nitrogen. Oxygen 1s^2 2s^2 2p^4, Nitrogen 1s^2 2s^2 2p^3
Both will gain electrons.
O2 - 1s^2 2s^2 2p^6, N3 - 1s^2 2s^2 2p^3
Both have the configuration of neon.
Prepare your data table.
In your data table, which mass values will be measured directly? Which mass values will be calculated? The mass of the magnesium and the mass of the magnesium products are calculated. Other mass values are measured directly.
Explain what must be done to calculate each mass value that is not measured directly. The mass of magnesium ribbon is calculated by subtracting the mass of the crucible from the mass of the crucible and magnesium. The mass of the magnesium products is calculated by subtracting the mass of the crucible from the mass of the crucible and its contents after heating.

1. Place the ring on the ring stand 7 cm above the Bunsen burner. Position...
