This gas makes up about 78% of Earth’s atmosphere.
What is nitrogen?
400
Much of benzene's stability is atributed to this property.
What is aromaticity?

In mass spec, this phenomenon is characteristic of ketones in which an alkene fragment is lost, and a radical enol cation is recorded by the detector.
What is the McLafferty rearrangement?
500
These highly reactive metals in Group 1 increase in reactivity as you move down the group due to decreasing ionization energy.
