Relationship of Pressure and Number of Gas Particles
This lesson uses awesome animations to describe what happens to the pressure inside a container as the number of particles is increased or decreased.
I always do the famous imploding soda can demonstration in this lesson to show what happens when the pressure exerted by gas particles inside an empty can is removed through heating heating water in the can and then inverting it in a tub of water.

Atomic Radius
This PowerPoint revisits the concept of periodic law and addresses the trend of atomic radius in a qualitative and quantitative analysis of elements in periods and rows.
The approach I take is to consider, for elements within a period, that elements have an increasing nuclear charge from left to right, but the same number of orbitals. Therefore, radius decreases.
For elements within a group, there are additional orbitals from top to bottom, so radius increases despite the increase in nuclear c

PreAP Chemistry Bonding FRQ
This contains 1 free response questions written in they style of AP. This question revolves around percent composition, empirical & molecular formula calculations, Lewis structures, molecular geometry, and polarity. Each successive part (8 individual parts here) of any FRQ potentially builds on itself and emphasizes a deeper understanding of the topic. The first page is the question which I give to students as part of their bonding test, but this could be used as a quiz, classwork, or homewor

Ionic Bonding, Ionic Radius, and Polyatomic Ions
This animated PowerPoint lesson discusses the ins and outs of ionic bonding: stability, octet attainment, electron transfer, increase of radius for nonmetals, decrease of radius for metals, and even polyatomic ions.
Most of my chemistry lessons are 8 slide PowerPoints. I print the PowerPoints each day (4 slides per page... front and back = 1 sheet of paper per student). The students then fill out the answers to my guided and scaffolded questions as I fill them out on the SmartBoard. My teaching
