Assume that the van der waals b constant for xenon (see table 1c.3- or 1.6 old version - van der waals coefficients) divided by avogadro's number represents the volume of a single xenon atom. assume that xenon atom is spherical, and estimate the radius (in meters) of a xenon atom using the formula vsphere = (4/3)rır3.

The estimated radius is 2.734*10^(-10) m.

Explanation:

If we assume the van der Waals constant b for Xenon divided by Avogadro's number gives the volume of a single Xenon, we have

We can express this volume in other units, more suitable for the size of an atom:

The volume of the sphere is

Then we can rearrange to clear r

The estimated radius is 0.2734 nm. As the problem ask for the radius to be in meters (1 nm = 10^(-9) m), we can multiply it by 10^(-9) and determine that the radius is 2.734*10^(-10) m.

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
