Beryllium has greater ionization energy, with 899 kJ/mol versus Germanium's 762 kJ/mol.
The general trend (most prominently displayed in the representative elements) in the Periodic Table is increasing ionization energy across a period, and decreasing ionization energy down a group.

Does calcium have higher ionization energy than beryllium?
Calcium: 589,9 kJ/mol. Beryllium: 899,5 kJ/mol.
What is the highest occupied energy level in the element Beryllium?
2s
Why is the first ionization energy of boron lower than beryllium?
The rise in ionisation energy is not regular. To explain this we must remember that the second shell of electrons is actually subdivided into 2s and 2p. The most easily removed electron in Boron is that in the 2p orbital, higher in energy than the 2s electrons in Beryllium. It therefore needs less energy for total removal than does the 2s electron of Boron. This outweighs the effect of the increased nuclear charge of Boron, which tends to make its outer electron harder to remove.
Alkali metal and alkaline earth metal have how many ionization energies?
Alkali metals (group 1 elements) have one valence electron. Hence have one ionization energy Alkaline earth metals (group 2 elements) have two valence electron. Hence have two ionization energy
What is beryllium's electron affinity?
It is NOT negative (for the first IE). Because Be's configuration is 1s2 2s2, we observe that it has no vacant orbital to accommodate an electron, meaning that to insert an electron, it has to go into a new sub-orbital, the higher-energy 2p. Hence, you need energy to promote this electron to a 2p level to force Be to accept it.
What is the first ionization energy of germanium?
The first ionization energy of germanium is 7.9 electron volts (eV).
What elements has the highest first ionization energy out of strontium magnesium beryllium calcium?
Beryllium will have the highest. Down a group ionization energy decreases.
Between beryllium and barium which element will have the lower ionization energy?
Barium has more energy levels. So it has lesser ionization energy.
Why does germanium has greater first ionisation energy than gallium?
Germanium has a greater first ionization energy than gallium because germanium has a smaller atomic size and thus a stronger nuclear charge, making it more difficult to remove an electron. Additionally, the electronic configuration of germanium (4d^10 5s^2 5p^2) is more stable compared to gallium (4d^10 5s^2 5p^1), resulting in a higher ionization energy.
What has the first largest ionization energy?
Helium has the highest ionization energy.
Why does germanium have a higher first ionization energy than Gallium?
Germanium has a higher first ionization energy than gallium because germanium has a smaller atomic size and higher effective nuclear charge, making it more difficult to remove an electron from germanium compared to gallium. This results in a higher energy requirement to remove the outermost electron in germanium, leading to a higher first ionization energy.
Does calcium have higher ionization energy than beryllium?
Calcium: 589,9 kJ/mol. Beryllium: 899,5 kJ/mol.
Why ionisation energy of boron is lower than beryllium?
The ionization energy of boron is lower than beryllium because removing an electron from boron involves taking it out of the 2p orbital, which is higher in energy than the 1s orbital of beryllium. This makes it easier to remove an electron from the 2p orbital of boron, resulting in a lower ionization energy.
Why does boron have a lower first ionization than beryllium?
Boron has a lower first ionization energy than beryllium because boron has an extra electron in a higher energy level, which results in increased shielding of the outer electron from the nucleus, making it easier to remove. Additionally, electron-electron repulsion in the larger boron atom contributes to the lower first ionization energy compared to beryllium.
What elements don't follow the trend for ionization energy?
Helium has a higher ionization energy than beryllium. Oxygen has a higher ionization energy than nitrogen.
Which of the group 3A elements has the largest ionization energy?
Beryllium is the group 3A element with the highest ionization energy.
Why boron has a lower first-ionization energy than beryllium?
Because in Boron there is a complete 2s orbital and the increased shielding of the 2s orbital reduces the ionisation energy compared to that seen in Beryllium.
