The Ionic Bond
An introduction to the noble gases shows how full electron shells on an atom makes an element unreactive. Your class will then develop an understanding of how sodium and chlorine react ideally because of their electron arrangement....
Curated OER
Electron Configuration
In this electron configuration worksheet, students write the electron configurations of 22 elements and compare their valence electron configurations. They list the elements that are similar in terms of their electrons. They identify the...

WS 5.5 Percent Composition
In this percent composition worksheet, students find the percentages of atoms in compounds and they determine empirical formulas given the percent of each atom in a compound.
Curated OER
Covalent Bonding
Using chlorine as the model to demonstrate the structures and representations, this PowerPoint clearly labels and details the main atomic structures and reasons for bonding. The electrons in the outer shell are diagramed and then the...
