Atom Bonding Lab
Introduction:
Atoms bond in covalent bonds and ionic bonds. A covalent bond is when atoms share electrons in order to gain stability with each other (Larsen). To have stability which each other, the atoms share electrons so that their outer electron shell is equal. Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions (Larsen, 2010). Element that have a positive ion are able to bond with elements with negative ions. This is because the elements share the electrons so that the ionization becomes neutral and both atoms become stable.
Materials:
1. Cards with elements and positive or negative ions.
2. Reference Tables for Physical Setting/CHEMISTRY 2011 Edition: Periodic Table of the Elements
3. Bond With a Classmate Worksheet
Procedure/Methods:
1. Pick an element card with a positive or negative ion out of the bag.
2. Find a classmate with an element with the opposite ion charge.
3. Mark on the paper the two elements, the compound formula, and the compound name.
4. Do this five times and then pick a new element from the bag.
5. Repeats steps 1-4 until you complete the table.
