Part 1: Why Do Atoms React?
Google Search
1. What is an atom?
An atom is the basic unit of a chemical element.
2. What is an element?
An element is a substance that is made entirely from one type of atom.
3. What makes an atom unstable (reactive)?
The binding energy not being strong enough makes an atom unstable (reactive).
4. Why do atoms react with other atoms?
Atoms react with other atoms to gain or lose electrons to fill their outer shell.
Part 2: Chemical Bonds
Go to http://www2.nl.edu/jste/bond.htm
1. What is an ion?
An ion is an atom that has gained or lost electrons.
2. What type of bonds do oppositely charged ions form?
Oppositely charged ions form ionic bonds.
3. A sodium ion is different than a sodium atom. It has a positive charge. How many protons and electrons does a sodium atom have?
Number of protons 11; Number of electrons 18
How about a chlorine ion? Number of protons 17; Number of electrons 18
4. What type of bond form when elements share electrons?
Covalent bonds form when elements share electrons.
5. Name a much weaker by important bond in living things.
A much weaker but important bond in living things is called a hydrogen bond.
