Macie Jones Question #4

How to determine ionic bonds:
An Ionic bond is a chemical bond in which one atom gives up an electron to another, forming two ions of opposite charges, and making an electrical force that holds the atom together. The atoms are then held together from the force of a positive charge and a negative charge pulling together.
If you were to look at the top right to the bottom left of the periodic table are most of where the ionic bonds take place. An ionic bond is typically formed between a metal and non metal.

Formation of the Molecule:
A molecule is formed when two or more of the same or different kinds of atoms join together. That new substance is called a compound. The number of protons is the same but the physical and chemical properties change because it is a new substance therefore giving it new properties.

Finding the bond:
First to see if the two substances are a metal or a non metal. Metals have 1,2, or 3 valence electrons. Non metals have 5,6 or 7 valence electrons. In ionic bonds there is an electron transfer. Metals give their extra valence electron or electrons to the non metals. When metals give and non metals recieve it becomes stable like a noble gas. This electron bond forms ionic bonds.
Covalent bonds form between two nonmetals. A nonmetal with 5,6 or 7 valence electrons share their electrons with other nonmetals with 5,6 or 7 valence electrons. They form a stable structure by electron sharing.

Experiment:
1. Obtain a conductivity meter.
2. Carefully place the conductivity meter into a solution.
3. Plug in the conductivity meter.
*** All metal components of meter are electrically charged! You will get shocked!!
4. Rate and record what you see in your lab notebook.
5. Unplug the conductivity meter.
6. Rinse off the conductivity meter prongs. Try next solution, repeating steps 1-6.
