We wish we had saved one of the first edition videos, for the sake of comparison. Now the videos stream and the CD seems no longer on offer. The animations in the original were huge for the time (hydrogen was about 12 megabytes), so downloading and saving them was a wise use of bandwidth-or one could buy a CD for $37 (20 pounds).
The current version is at least the second.

I one shines x-rays through the crystel onto a sensor, such as a sheet of photographic film, a pattern of spots. Using only the periodic table arrange the following elements in order of increasing atomic radius: selenium, polonium, tellurium, sulfur. The atoms in a crystel are arannged in a regular pattern.

Compared with the atomic radius of oxygen (Z 8), the atomic radius of sulfur (Z 16) is. We know it has a posoitively charged center (the nucleus), which is surounded by mving electrosn.
