Just as learning to read starts with the alphabet, so it is with chemical bonding and nomenclature. And once you learn it, you can not forget it. Just as reading you never forget the alphabet. So learn it very very well and deeply.
More than one atom bonded together makes a molecules. The ionic and covalent bonds are the two types of bonds that form molecules. Both types have their own system of naming or nomenclature.
(November 2017) The extreme and brute force transfer of electrons and consequential opposing charges attracting to form ionic bonds and ionic compounds.
(November 2017) Here is a worksheet going from both name to molecular formula and in the reverse. Both are following very strict rules. So learn it first and practice the problems from your text. Then try these and don't look at the answers until you've done an honest attempt. Be sure to get the entire correct answer.
(November 2017) The subtle and less dramatic sharing of electrons to form covalent bonds and covalent compounds.
(November 2017) The 3D geometry of molecular or covalent compounds is more easily understood when it is visualized in three dimensions.
(November 2017) This is the covalent compounds worksheet. You'll really want to focus on getting the right Lewis Structure, Geometry, and polar/nonpolar correct. The answers are not included because I want you to learn how to find the right answers from the internet and your text. If from the internet, learn to verify that the webpages you're using are giving you the correct answers.
Part of verifying on the internet will be that the internet is not always right, or is out of context.
