Question

iron has higher enthalpy of atomisation than copper

Answer 1

The energy needed to remove one or more electrons from a neutral atom to form a positively charged ion is a physical property that influences the chemical behavior of the atom. By definition, the first ionization energy of an element is the energy needed to remove the outermost, or highest energy, electron from a neutral atom in the gas phase.

The process by which the first ionization energy of hydrogen is measured would be represented by the following equation.

H(g) H+(g) + e-



Ho = -1312.0 kJ/mol

 

Answer 2

The answer is True.

At any point of time, iron always has higher enthalpy of atomization than copper. Enthalpy of atomization is dependent on how many unpaired electrons are present in the outermost shell of an element. This is more in the case of iron when compared to copper. As a result, iron has stronger interatomic interaction and metallic bonds.
