Question

why the second ionization enthalpy is greater than the first ionization enthalpy? What are the transuranium elements? ​

Answer 1

Answer:

The reason is the second ionization enthalpy is higher than the first relates to the attraction between the electrons and the nucleus. When one electron is removed from an atom, the neutral atom becomes positive...... Thus, the second electron is harder to remove and the ionization requires more energy.

The transuranium elements are the chemical elements with atomic numbers greater than 92, which is atomic no. of uranium.
