Module: Foundations Activity: Animations Title: Chemical Bonding

Introduction
1. Why are chemical bonds important? They form the structure and function of molecules in the body
2. a. Describe atomic structure. Whether or not the atom is positive or negative, the ions orbiting around the atom.

b. Explain the importance of the outer (valence) electrons relative to bonding.

combine to form chemical bonds

Covalent Bonds
3. First, explore covalent bonds.
a. Describe the electron activity. Formed when two atoms fill the outermost shell from sharing electrons
b. Describe an oxygen molecule as an example. Two oxygen atoms share the outermost electrons …show more content…

Describe the electron activity. Formed when electrons move from atom to atom to form ions
b. Why do chlorine and sodium have charges after electron transfer? Sodium atom lost an electron now it has a positive charge because the protons are greater than electrons. Chloride gains the electron so there is a negative charge because electrons are greater than protons.
c. What causes the attraction between ions forming an ionic bond? By opposite charges of both ions
d. Describe the "strength" of ionic bonds. Use salt as your example. Ionic bonds are weak, that’s why salt can dissolve in liquids
e. How common is ionic bonding in the body? Extremely common. Our teeth and bones are aided by ionic bonding
f. How are ions important to the body? Examine each of the following in your research.
Nerve impulses - ions generate nerve impulses pH regulation - each ion has a positive or negative charge that helps in keeping our PH normal
Bone formation – each ion composes the correct amount of bonds to form bones and teeth
Hydrogen Bonds
1. Explain why water molecules have positive and negative "poles." The oxygen electrons are attracted to like electrons creation some negative charge on the oygen and positive on
