Why is MgH2 ionic?
Why is MgH2 ionic?
It all depends on the difference of electronegativities of elements in a compound. The convention (not an absolute rule that one can derive) is that if the EN difference is greater than 1.7, the compound is ionic; if less covalent. Therefore, one can describe both, BeH2 and MgH2 as partly ionic compounds.
How do you know if bonding is ionic or covalent?
Classifying compounds as ionic or covalent
- If a compound is made from a metal and a non-metal, its bonding will be ionic.
- If a compound is made from two non-metals, its bonding will be covalent.
