Do not proceed to schedule a custom demo unless you have already conferred with the lecture demonstrator about it. The custom demos section of the website is used by UO chemistry instructors to schedule demonstrations that are not listed in the database.

Figure 8.23 Atomic Radii Trends on the Periodic Table shows spheres representing the atoms of the s and p blocks from the periodic table to scale, showing the two trends for the atomic radius. This is because while the number of electrons increases down the period, they only add to the same main energy level, and therefore do not. For example, ionization energy, electronegativity, and of course atomic radius which we will discuss now. This web site is provided on an "as is" basis. Again, we can summarize this trend as follows: as PT, atomic radius. There are many trends on the periodic table. (b) Covalent radii of the elements are shown to scale. Although the concept of a definite radius of an atom is a bit fuzzy. Because it is impossible to measure the sizes of both metallic and nonmetallic elements using any one method, chemists have developed a self-consistent way of calculating atomic radii using the quantum mechanical functions. The atomic radius is an indication of the size of an atom. "Do not do demos unless you are an experienced chemist!" The atomic radius for the halogens increases down the group as n increases. There may be a few points where an opposite trend is seen, but there is an overall trend when considered across a whole row or down a whole column of the periodic table.
