what does covalent character of beryllium mean?

btw when looking for carbon in data booklet , do we look at diamond or graphite?

it means that in beryllium compunds, say BeI₂ there is a high degree of covalent character because beryllium is a small, highly charged ion which ploarises the iodide ion and makes a partly covalent bond. Normally, metals and non metals make ionic compounds, but when you have a highly polarizing metal ion together with a highly polarizable non metal ion, you get a significant amount of covalent bonding too (which makes the bond stronger)

The "natural" state of carbon (when looking up data) is graphite.

Isn't the natural state of carbon amorphous?

Isn't the natural state of carbon amorphous?

Standard state of carbon at 298K is graphite. You'll learn that with Mano in Thermodynamics lectures next year, provided you make your offer! (Good luck!)
