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 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.
What has the first largest ionization energy?
Helium has the highest ionization energy.
What is the first ionization energy of germanium?
937 Kilojoules/mole
Which of the group 3A elements has the largest ionization energy?
Beryllium is the group 3A element with the highest ionization energy.
Which is greater the second ionization energy of potassium or that of calcium?
potassium is greater in the second ionization energy.
Does calcium have higher ionization energy than beryllium?
Calcium: 589,9 kJ/mol. Beryllium: 899,5 kJ/mol.
What is the energy level for germanium?
The energy level for germanium is 4. You know its 4 because of the period its in for example: beryllium is in row 2 period 2 so the energy level is 2.
What is the element with the highest ionization energy?
fluorine bromine chlorine
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.
Is it ionization energy is a periodic property?
Ionization energy generally increases across a period as a result of a higher nuclear charge, however there are some exceptions such as Boron which has a lower ionization energy than Beryllium (because it is in a P orbital), and Oxygen which has a lower ionization energy than nitrogen (Because ionization decreases the electron electron repulsion in its orbitals).
Why does the second ionization energy of Group 1 Elements greater than the first ionization energy of Group 1 Elements?
It takes more energy to knock off two electrons
