According to the kinetic molecular theory, which statement describes the particles in a sample of an ideal gas?

The motion of the gas particles is random and in a straight-line. A sample of gas is contained in a closed rigid cylinder.

I hope this helps you if not soo advance sorry :)

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
