is a covalent compound because sharing of electrons takes place between hydrogen and phosphorus. Both the elements are non-metals and hence, will form covalent bond.
The nomenclature of covalent compound is given by:
- The less electronegative element is written first.
- The more electronegative element is written then, and a suffix is added with it. The suffix added is '-ide'.
- If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on..
Hence, the name for is phosphorus trihydride.
