 * Questions:
 * 1) What is a covalent bond? a form of chemical bonding that is characterized by the sharing of pairs of electrons between atoms, and other covalent bonds []
 * 2) What is an ionic bond? a type of chemical bond that involves a metal and a nonmetal ion through electrostatic attraction []

 * 1) List 5 differences between ionic and covalent compounds (Ex. high or low boiling and melting points, sharing or transferring electrons, etc.). ionic compounds are formed from metals and nonmetals and covalent compounds are formed from a nonmetal and another nonmetal, ionic compounds have a high melting and boiling point and covalent compounds have a low melting and boiling point, ionic compounds are Crystalline Solids at RTP and covalent compounds are gas or liquids at RTP, ionic compounds transfer electrons and covalent compounds share valence electrons, and ionic compounds are crystals as where, covalent compounds are molecules From: worksheet

 * __Guide to Naming and Writing Formulas__**

1.H2S hydrosulfuric acid The formula is an acid because it follows the formula HnX and it has an H+. It follows rule #1 which stats that when the name of the anion ends in -ide, the acid name begins with the prefix hydro, has the suffix -ic and is followed by the word acid.

2.sodium sulfate Na2SO4 The name has a metal so, its ionic.Then, I looked at the perodic table and found that sodium has a charge of 1+ and that sulfate has a charge of 2-. Last, I flipped the charges so that sodium has a charge of 2- and sulfate has a charge of 1+(you don't write the charge of 1+).

3.sulfuric acid H2SO4 The name is an acid because it has a suffix of -ic followed by the word acid. I found the formula by rule #3 which stats that when the anion ends in -ate, the acid is the stem of the anion with the suffix -ic followed by the word acid.Then because of this the name had to be sulfate and the charge of sulfate is 2- and in an acid the charge of a hydrogen atom is always 1+.So in order to get the formula you had to switch the charges to get H2SO4.
