Assertion: Beryllium has higher ionization energy compared to the other Group 2 elements.
Reason: Beryllium has a small atomic radius and a high nuclear charge, which results in a strong attraction between the nucleus and valence electrons.
Both assertion and reason are true, and the reason is the correct explanation of the assertion.
Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
The assertion is true, but the reason is false.
Both assertion and reason are false.
Answers (1)
Beryllium has a smaller atomic radius compared to the other Group 2 elements due to its higher nuclear charge and a smaller number of electron shells. This results in a stronger attraction between the nucleus and valence electrons, making it more difficult to remove an electron from the atom, leading to a higher ionization energy
-
Beryllium exhibits anomalous behaviour compared to other elements in Group 2 due to its small size and high charge density.
-
It has a higher melting and boiling point, as well as a higher ionization energy, compared to the other group members.
-
Additionally, while the other elements in the group form oxides with the general formula MO, beryllium oxide (BeO) is largely covalent and has a different structure.
-
Finally, beryllium is more soluble in water and forms complex ions in the solution.
-
These anomalous properties can be attributed to their small size and high charge density, leading to stronger bonding and unique electronic configurations.
