1.What is a covalent bond?
 * A chemical bond that shares a pair of electrons between atoms in a moecule.

2. What is an ionic bond?
 * A type of chemical bond that involves a metal and nonmetal ion.

3. List 5 differences between ionic and covalent compounds (Ex. high or low boiling and melting points, sharing or transferring electrons, etc.).
 * An Ionic compound is between a metal and nonmetal and a covalent compound is between two or more nonmetals. An ionic compound is a sold crystal at room temperature and covalent compound at room temperature is a gas or liquid. A covalent compound shares electrons and an ionic compound transfers electrons from metals to nonmetals. An ionic comound condycts electricity when dissolved or melted, a covalent compound doesn't. Ionic compounds tend to have high melting and boiling points and covalent bonds tend to have low ones.

 * __Guide to Naming and Writing Formulas for Chemical Compounds__**

(Given) Na2SO3 - Name: Sodium sulfite
 * Since this compound includes the metal Sodium its an ionic compound, so you don't need prefixes because no prefixes are needed in ionic compounds. Na is Sodium and SO3 is Sulfite.



(Given) ZnO - Name: Zinc (II) oxide
 * Since this compound includes the metal Zinc it's an ionic compound and doesn't need prefixes. Then i named the compounds Zn is Zinc and O is oxide and since Zinc is a transition metal so it needs a roman numeral. The roman numeral would be three becuse the charge is -3 on oxygen.



(Given) HClO - Name: Hypochlorous acid
 * I used rule number 2 to help me name this acid because it says you have to change the -ite ending and replace it with -ous then acid to the name.



(Given) Perchloric Acid - Formula: HClO4
 * The first part if the name Perchlor- tells you what that first part of the compound which is ClO3- and the word acid at the end tells you its bonded it H like all acids.
