Aluminum's enthalpy of vaporization is 284 kj/mol. beryllium's enthalpy of vaporization is 224 kj/mol. in which element is the bonding stronger between atoms?

Enthalpy is the energy needed for the phase change called vaporization. It is the energy needed to break the bonds of the liquid molecules so that it can be converted to its gaseous form. Therefore, the greater the value of the enthalpy is, the stronger are the bonds of the substance. Therefore, the answer is Aluminum.
