The third ionization energy of calcium is greater than that of potassium because calcium has a higher effective nuclear charge and a more compact electron configuration. When removing the third electron from calcium, it involves removing an electron from a more stable, fully filled subshell (3s²) after two electrons have been removed. In contrast, potassium's third ionization energy involves removing an electron from a less stable configuration (4s¹), making it easier to remove. Consequently, the energy required to remove the third electron from calcium is higher.

What is lowest second ionization energy on argon calcium or potassium?
calcium
Ionization energy of Ca?
The ionization energy of calcium (Ca) is the energy required to remove one electron from a neutral atom of calcium in the gaseous state. The first ionization energy of calcium is approximately 590.6 kJ/mol, indicating the energy needed to remove the outermost electron. Additional ionization energies are required to remove subsequent electrons.
How does calcium first ionization energy compare to the first ionization energy of magnesium and potassium?
Calcium's first ionization energy is lower than that of magnesium but higher than that of potassium. This is due to the increasing atomic size down the group, which decreases the effective nuclear charge felt by the outermost electron. Magnesium, being higher in the group, has a smaller atomic radius and a stronger attraction between the nucleus and its valence electron, resulting in a higher ionization energy. Conversely, potassium, being further down the group, has an even larger atomic radius, leading to a lower ionization energy than calcium.
Does barium has lower ionisation energy than calcium?
Yes, barium has a lower ionization energy than calcium. This is because barium is located further down in Group 2 of the periodic table, meaning it has more electron shells and greater electron shielding. As a result, it requires less energy to remove the outermost electron compared to calcium, which is higher up in the group.
How does calcium's first ionization energy compare to the first ionization energy of magnesium and potassium?
First ionization energy of magnesium = 870/ kj/mol First ionization energy of phosphorous = 589 kj/mol So, magnesium has the larger ionization energy required to pull the first valance electron. Do you know why?
Which is greater the second ionization energy of potassium or that of calcium?
The second ionization energy of calcium is greater than that of potassium. This is because calcium, with its higher nuclear charge and smaller atomic size compared to potassium, holds onto its electrons more tightly.
Does calcium have a lower first ionization energy level than sodium?
No. Calcium has TWO valence electrons, and Sodium has ONE. It is lot easier to take off one, than two you see. However, the second ionization energy of calcium IS however than the second ionization energy of Sodium. ;)

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.
Which has a greater ionization energy beryllium or germanium?
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.

What has the highest first ionization energy phosphorous calcium sodium or aluminum?
Phosphorus has the highest first ionization energy among phosphorus, calcium, sodium, and aluminum. This is because phosphorus has a higher effective nuclear charge compared to the other elements, making it more difficult to remove an electron from its outer shell.
What do we mean by the first second third ionization energies for a particular atom?
First ionization energy is the energy required to remove the first outermost electron from an atom. The second ionization energy is the energy required to remove the next available electron, and is greater than the first IE. The third IE is that energy needed to remove the third electron, and is greater the the second IE.
