What is the main difference between protons and neutrons?
O Protons have a much smaller mass than neutrons.
O Protons have a much larger volume than neutrons.
Protons have an electrical charge, but neutrons have no charge.
O Protons make up the nucleus, but neutrons orbit around the nucleus.

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
