In the gaseous state, the distance between the molecules is _ times _ than their diameters.

Correct answer: C. 300, greater

A. 200, lesser
B. 300, lesser
C. 300, greater
D. 200, greater

Explanation

About Atomic Structure

Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
