Two argon atoms form the molecule Ar2 as a result of a van der Waals interaction with U0 = 1.68×10-21 J and R0= 3.82×10 the frequency of small oscillations of one Ar atom about its equilibrium position.

Explanation:

From the given information:

The elastic potential energy can be calculated by using the formula:

Making K the subject;

k = 2.3 × 10⁻² N/m

Now; the frequency of the small oscillation can be determined by using the formula:

where;

m = mass of each atom = 1.66 × 10⁻²⁶ kg

statement #3 on andre"s list is false.
