Explain why a covalent bond forms, how it forms, and what types of elements form them.
Covalent bonds form to make elements more stable., Two nonmetals share electrons.
Differentiate between the properties of covalent compounds and ionic compounds.
Differentiate between the properties of covalent compounds and ionic compounds. Covalent compounds: low melting and boiling points, usually gases or dull or brittle solids, do not conduct electricity in water. Ionic compounds: high melting and boiling points, usually solid crystals, do conduct electricity in water.

Oxidation number
The charge on an ion
Explain why elements form compounds, and what most elements need to achieve this. Include which elements do not tend to form compounds and why.
To be stable, 8 valence electrons, Noble gases.
Explain why an ionic bond forms, how it forms, the two parts that make it up, and the overall charge of the resulting compound.
To make elements more stable, a metal (cation) transfers its valence e- to a nonmetal (anion), overall charge is 0
Al2O3
aluminum oxide
(NH4)2SO4
ammonium sulfate
Octet rule
atoms will gain, lose, or share electrons in order to have 8 electrons in their outer shell.
Covalent Bond
bond that results from the sharing of electrons between two nonmetals.
Ions
charged atom that has gained or lost electrons.
Molecule
compound formed when 2 or more elements bond covalently.
chemical bond
force that holds atoms together in a compound.

magnesium hydroxide
What is an anion?
negatively charged ion formed from gaining e-
What is an cation?
positively charged ion formed from losing e-

chemical formula
tells what elements and how many of each element are in a unit of that compound.
Compound
two or more elements chemically combined.
Ionic bond
when atoms transfer electrons in order to be stable.
