What else can I help you with?
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 element in period 3 has the lowest first ionization energy?
Sodium (Na) has the lowest first ionization energy in period 3.
What are the ionisation enthalpies of potassium and sodium?
The first ionization energy of potassium is 419 kJ/mol, while the first ionization energy of sodium is 496 kJ/mol. This means that it requires less energy to remove an electron from a potassium atom compared to a sodium atom.
Which of the elements sodium calcium potassium and magnesium has the smallest first ionization energy?
Potassium has the smallest first ionization energy among those elements listed. This is because potassium has the largest atomic size and the weakest attraction between its nucleus and outermost electron, making it easier to remove that electron.
What is the first ionization energy for sodium?
Na(g) --> Na+(g) + e- First ionisation energy is always: X(g) --> X+(g) + e- with X being an element
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 is first ionization energy?
Sodium's first ionization energy is 495 kJ / mol.
What element in period 3 has the lowest first ionization energy?
Sodium (Na) has the lowest first ionization energy in period 3.

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.
What is the first ionization energy for sodium?
Na(g) --> Na+(g) + e- First ionisation energy is always: X(g) --> X+(g) + e- with X being an element
The amount of energy required to remove one mole of electrons from one mole of sodium atoms is the?
The amount of energy required to remove one mole of electrons from one mole of sodium atoms is known as the ionization energy. In the case of sodium, the first ionization energy is approximately 495.8 kJ/mol. This energy is needed to remove one electron from a sodium atom to form a sodium cation.
Does sodium have the larger first ionization energy than potassium?
No, potassium has a larger first ionization energy than sodium. Potassium has an extra electron in its valence shell compared to sodium, making it more difficult to remove an electron from a potassium atom compared to a sodium atom.
Which has higher first ionization energy aluminum or sodium?
Aluminum has a higher first ionization energy than sodium. This is because aluminum is located further to the right in the periodic table, where elements generally have higher ionization energies due to increased nuclear charge and the effective nuclear attraction on electrons. Sodium, being an alkali metal, has a lower ionization energy as it has a single electron in its outer shell that is more easily removed.
Which element has a lower first ionization energy than element S?
Element P (phosphorus) has a lower first ionization energy than element S (sulfur).
Which is more reactive sodium or barium?
sodium because it's the first group and first group are the most
