**Explanation:**

The correct statements are:

a) Ionization energy increases for each successive electron removal.
b) The greatest increase in ionization enthalpy is experienced on removal of electron from the case of noble gas.
c) End of valence electrons is marked by a big jump in ionization enthalpy.

**a) Ionization energy increases for each successive electron removal:**

Ionization energy refers to the energy required to remove an electron from an atom or ion in its gaseous state. As we move across a period in the periodic table, the ionization energy generally increases. This is because the effective nuclear charge (the positive charge experienced by the outermost electrons) increases, resulting in a stronger attraction between the nucleus and the electrons. Therefore, it becomes more difficult to remove an electron as we move from left to right across a period.

**b) The greatest increase in ionization enthalpy is experienced on removal of electron from the case of noble gas:**

Noble gases have a completely filled valence shell, which makes them highly stable. The removal of an electron from the outermost energy level of a noble gas requires a significant amount of energy. This is because removing an electron would result in an incomplete valence shell, which is energetically unfavorable. As a result, the ionization energy of noble gases is significantly higher compared to other elements in the periodic table.

**c) End of valence electrons is marked by a big jump in ionization enthalpy:**

The valence electrons are the electrons present in the outermost energy level of an atom. As we move across a period in the periodic table, the number of valence electrons generally increases. When we reach the end of a period, there is a big jump in ionization enthalpy. This is because the removal of an electron from the outermost energy level results in a stable, completely filled energy level below it. This increased stability leads to a greater ionization energy compared to removing electrons from the partially filled energy levels before it.

**d) Removal of electron from orbitals bearing lower n values is easier than from orbital having higher n value:**

This statement is incorrect. The ionization energy generally increases as we move from lower n values to higher n values within a given period of the periodic table. This is because the outermost electrons in orbitals with higher n values are farther away from the nucleus, resulting in a weaker attraction between the nucleus and the electrons. Therefore, it requires more energy to remove an electron from an orbital with a higher n value compared to an orbital with a lower n value.

In summary, the correct statements are a) Ionization energy increases for each successive electron removal, b) The greatest increase in ionization enthalpy is experienced on removal of electron from the case of noble gas, and c) End of valence electrons is marked by a big jump in ionization enthalpy.
