Hello,
So, I was under the impression that metals and non-metals only bond ionically. However, Jssoussou mentioned the covalent bonding of Be and Cl...

Would someone care to enlighten me?
Many thanks.

On a more mundane level anhydrous aluminium chloride is covalent at room temperature and above.

So all you need is a metal that's got a lot polarising power, i.e. small and highly charged e.g. Be or Al and a non-metal that's not that electronegative i.e. large e.g. I.
I wonder what type of bonding BeI has...

There's a continuous spectrum from ionic to covalent, depending on how well separated the charge is (fully ionic=fully separated, fully covalent=completely shared).

Yes, it is. It is possible, if the charge difference (electronegativity) between the non-metals and metals is not to high. Otherwise the attraction of one of the charge is so strong that electrons will be donate and accept by one of the atoms, and then its an ionic bond.

There is no such thing as a 100% ionic compound. Since polarisation of ions and ions are not perfect point charges, there is always a slight degree of covalent character.
Whilst some ionic compounds have such a difference in electronegativity that we can assume completely ionic bonding, this technically is not totally true.
