Among the following elements element with highest ionisation enthalpy ...
Explanation:
Ionization enthalpy is the energy required to remove an electron from an isolated gaseous atom to form a cation. The element with the highest ionization enthalpy would require the most energy to remove an electron.
Key Points:
- Ionization enthalpy generally increases across a period from left to right in the periodic table.
- This is because as you move across a period, the effective nuclear charge increases, leading to a stronger attraction between the nucleus and the valence electrons.
- Among the given elements (Nb, C, O, B), Nb (Niobium) has the highest atomic number.
- Niobium (Nb) being a transition metal has more tightly held electrons due to the presence of inner d and f orbitals, resulting in a higher ionization enthalpy compared to the other elements.
Therefore, the element with the highest ionization enthalpy among the given options is Nb (Niobium).
