You're on track to learn more about chemical bonds and how they work. Your biggest friend when it comes to understanding chemical bonding is the periodic table because it's organized to group elements with similar charges together (for example, all of the alkali metals carry a +1 charge). Electronegativity is a periodic table trend. Atoms with the same electronegativity form nonpolar covalent bonds. Atoms with similar but not identical electronegativity (two different nonmetals) form polar covalent bonds. When the electronegativity difference is large (think metals with nonmetals), you get ionic bonds.

When you balance chemical formulas, remember the electrical charges cancel out. So, if you have two positive charges, you form a neutral compound if it bonds with two negative charges.

From here, you might want to review the types of chemical bonds and how chemical formulas work. If you're ready for another quiz, see if you understand the basics about atoms and their parts.

Bravo! You understand how chemical bonds form and how electrons are transferred or shared to form ions and compounds. If you're ever in doubt about the type of bonds formed between atoms, look at their position on the periodic table. Atoms with the same electronegativity (like two oxygen atoms) form nonpolar covalent bonds. Atoms with close electronegativity values (like two nonidentical nonmetals) form polar covalent bonds. If the electronegativity difference is large (between a metal and a nonmetal) then ionic bonds form.

From here, you can test yourself to see if you know the trends in the periodic table or you might wish to review the types of chemical bonds.
