There are two important isotopes of uranium: 235U and 238U. These isotopes have different atomic masses and react differently. Only 235U is very useful in nuclear reactors. One of the techniques for separating them (gas diffusion) is based on the different rms speeds of uranium hexafluoride gas, UF6. a)The molecular masses for UF6 with 235U and UF6 with 238U are 349.0 g/mol and 352.0 g/mol, respectively. What is the ratio of rms speeds?

Diatomic Gas

Molecule, is a collection of two or more atoms together (which constitute the smallest observable unit) into a pure material. There are some ways to represent the structure of a molecule. Factor symbols represent atoms in Lewis structures, and dots represent electrons that accompany them. A pair of mutual electrons (covalent bond) may be represented by a single dash. The ball-and-stick model depicts the spatial structure of the atoms better.
