Answer:
Electronegativity = 1.87.
Ionic radius = 109 pm.
Atomic radius = -39 pm
First ionization energy = 410 kJ/mol
Explanation:
Hello!
In this case, since electronegativity, ionic radius, atomic radius and first ionization energy are periodic properties that have specific trends, we can summarize it by realizing that oxygen and beryllium belong the same period 2 and differ in group, 6A and 2A respectively.
In such a way, the required comparison is written below:
Electronegativity = 3.44 (oxygen) - 1.57 (beryllium) = 1.87.
Ionic radius = 140 pm (oxygen)- 31 pm (beryllium) = 109.
Atomic radius = 73 pm (oxygen) - 112 pm (beryllium) = -39 pm
First ionization energy = 1310 kJ/mol (oxygen) - 900 kJ/mol (beryllium) = 410 kJ/mol
It means that electronegativity, ionic radius and first ionization energy increases from left to right whereas the atomic radius from right to left.
Best regards!
Oxygen and Beryllium are the elements that pertain to the same period and different groups 6A and 2A.
Ionic radius, atomic radius, electronegativity and first ionization energy are periodic qualities that have selective trends.
Differences in the trends are:
- Ionic radius = 109 pm
- Atomic radius = -39 pm
- Electronegativity = 1.87
- First ionization energy = 410 kJ/mol
This can be explained as:
- Ionic radius:
= 140 pm (oxygen)- 31 pm (beryllium)
= 109.
- Atomic radius:
= 73 pm (oxygen) - 112 pm (beryllium)
= -39 pm
- Electronegativity:
= 3.44 (oxygen) - 1.57 (beryllium)
= 1.87
- First ionization energy:
= 1310 kJ/mol (oxygen) - 900 kJ/mol (beryllium)
= 410 kJ/mol
Therefore, these data tell that ionic radius, electronegativity and first ionization energy increases from left to right in a period whereas, the atomic radius increases from right to left in a period.
