Question

Is `BeF_2` ionic or covalent?

Answer 1

Ionic.

Explanation:

All we have to do is identify the elements present in this compound.

Generally, a metal (cation) and a non-metal (anion), will form an ionic compound.

A compound formed between non-metals are generally covalent compounds.

Here, we have `Be` and `F`. By looking at a periodic table, we see that `Be` is a metal and `F` is a non-metal.

Therefore, `BeF_"2"` is an ionic compound.

Hope this helps :)
