Answer: The covalent bonds within a molecule are very (strong). However it requires (less) energy to melt a molecular compound than an ionic compound.
This is because the attractive forces between individual molecules are (weaker) than the forces between ions in an ionic compound.
PH3 looks just like ammonia NH3 with a lone pair and 3 hydrogens in a pyramidal formation.
<span>In PH3 the P has 3 bond pairs and 1 lone pair, (4 total pairs). The shape is called trigonal pyramidal (approximately tetrahedral minus one atom).
