Comparison of Beryllium and Boron:

Beryllium:
- Beryllium has lesser nuclear charge compared to boron.
- Beryllium has greater first ionisation enthalpy compared to boron.

Boron:
- Boron has greater nuclear charge compared to beryllium.
- Boron has lesser first ionisation enthalpy compared to beryllium.

Explanation:
- The nuclear charge of an atom is determined by the number of protons in its nucleus. Beryllium has 4 protons in its nucleus, while boron has 5 protons. Therefore, boron has a greater nuclear charge compared to beryllium.
- The first ionisation enthalpy is the energy required to remove the outermost electron from an atom. Beryllium has a greater first ionisation enthalpy compared to boron because beryllium's outer electron is closer to the nucleus and experiences a stronger attraction, making it more difficult to remove.

Therefore, in comparison to boron, beryllium has lesser nuclear charge and greater first ionisation enthalpy.
