- Of all alkaline earth metals known to us, Beryllium is the lightest of all. The metal sits in 4th place on the periodic table, but when it comes to abundance on Earth, it takes the 44th. Compared to steel's specific stiffness, Beryllium's specific stiffness is 6x more.

Neon is about two-thirds as denser as air. Neon is the second lightest inert gas, as well as being the second-lightest noble gas after helium. It has three stable isotopes. Georges Claude began creating neon lighting in 1902.
- Although many Sulphur compounds have a strong smell, the pure element is odorless. At room temperature and pressure, sulfur is a yellow solid.
