Atomic radius

Van der Waals radius

The van der Waals radius, rw, of an atom is the radius of an imaginary hard sphere representing the distance of closest approach for another atom. It is named after Johannes Diderik van der Waals, winner of the 1910 Nobel Prize in Physics, as he was the first to recognise that atoms were not simply points and to demonstrate the physical consequences of their size through the van der Waals equation of state. (Wikipedia).

Maximum Voltage of a Van de Graaff Generator

How to determine the maximum voltage attainable with a Van de Graaff generator. Note near the end of the video I refer to the diameter of the gazing ball, the round sphere, as 10 cm. The radius is about 10 cm, not the diameter.

Polymer shapes (length and radius)

Polymers are often long chains of repeat units. A simple picture shows them lined up. What would the length be if it from end to end? We can calculate this length is we know the individual bond lengths, the number of bonds, and the bond angle. However, although bonding may favor lining up
