The noble gases show trends in their physical properties.
The noble gases all have low boiling points:
This is because, going down group 0:
The particles in gases are widely spaced, so the noble gases have low densities:
Oganesson, Og, was discovered in 2002. It is placed below radon in group 0. Assuming that it is a gas at room temperature, predict its density and explain your answer.
About 16 g/cm3 because density increases going down group 0, and the difference increases from one element to the next.
The noble gases are all inert - they are extremely unreactive. Unlike elements in other groups, their atoms have complete outer shells. This means that atoms of the noble gases have no tendency to lose, gain, or share electrons. When other elements react, their atoms complete their outer shells by losing, gaining, or sharing electrons.
