All the constituent elements in triethylamine are nonmetals; Nitrogen, Carbon and Hydrogen. Its formula is N(CH2CH3)3.
The rule is that if it is nonmetal to nonmetal the bond is covalent, if it is nonmetal to metal then it is ionic. (except in acids)
So it is covalent.
Quick tip: Amine is a group of organic chemicals, all organic chemicals have CHO and N and therefore are covalent (except in acids). Ethyl is just a ethane group without a hydrogen and instead a bond to another element and tri just says that there are 3 ethyl groups.
This is an ionic compound.
