Product Description
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 charge.

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 style is highly interactive, and my lessons support that style.

All lessons include a Do Now, Mini Lesson, Pair Up, and Summary to keep students moving and engaged.

To remove the "Wickline" watermark, select the Watermark from the Insert menu, then select No Watermark. You cannot remove the watermark's from .pdf files and SmartBoard files, so you'll have to make new ones from your fresh watermark-less Microsoft file.
