 * 1) What is a covalent bond?
 * 2) What is an ionic bond?
 * 3) List 5 differences between ionic and covalent compounds (Ex. high or low boiling and melting points, sharing or transferring electrons, etc.).
 * 4) Find 5 Lewis Structures and copy and paste them on your page. Determine their molecular geometry.

1. A chemical bond that involves sharing a pair of electrons between atoms in a molecule. 2. Chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion. 3. 1. In a Covalent compund atoms share electrons. 2. in an Ionic compound Atoms are bonded together. Ionic compounds are usually a metal and nonmetal. Covalent - 4. Picture one is Square Planar. Picture two is Tetrahedral. Picture three is Linear. Picture four is Bent.



1. Ca(OH)2 = Calcium Hydroxide. First i looked at the Periodic Table for calcium which is in group 2A. So the charge on that would be 2+. Then i looked at this sheet that has polyatomic ions and found OH. which is hydroxide, and hydroxide has a 1-. charge. So by looking at the formula i was given Ca(OH)2. i realized that the charges were crossed. which made the rest easy to figure out.

2. Hydroselenic Acid = H2Se. Fisrt I found Selenium on the periodic table which is in group 6A. So the charge is 2-. the charge on hydrogen is a 1+. Lastly, I crossed my charges and got H2Se.

3. H3P = Hydrophosporic Acid. P stand for phosphorus on the periodic table. Phosphorus is in group 5A, so its charge is 3-. Hydrogens is 1+. I realized charges were crossed.
