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.

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.
Why is the flame of beryllium colourless?
The flame of beryllium is colorless because beryllium does not emit visible light when it is heated. Unlike other metallic elements that can produce characteristic flame colors due to electronic transitions, beryllium’s electronic structure does not allow for such transitions in the visible spectrum. Instead, any energy absorbed may result in excitation of electrons to higher energy states, but these transitions involve higher energy photons, which are outside the visible range. As a result, beryllium appears to burn without producing a colorful flame.
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 the ionization energy of beryllium?
The ionization energy of beryllium is 899.5 kilojoules per mole.
What has greater ionization energy lithium or berylium?
Beryllium has a greater ionization energy than lithium. This is because beryllium has a higher nuclear charge and a smaller atomic radius, which leads to a stronger attraction between the nucleus and the valence electrons. As a result, it requires more energy to remove an electron from beryllium compared to lithium.
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?
There are two main elements that do not follow the trend for ionization energy. Those two elements are both Boron and Oxygen.
