What are the ionisation enthalpies of potassium and sodium?
First ionization energy of sodium is 495,8 kJ/mol.First ionization energy of potassium is 418,8 kJ/mol.
What has the highest first ionization energy phosphorous calcium sodium or aluminum?
Phosphorus. Across the period, first ionization energy increases.
Which of the elements sodium calcium potassium and magnesium has the smallest first ionization energy?
Sodium
Does sodium have the larger first ionization energy than potassium?
yes, it does
What element in period 3 has the lowest first ionization energy?
Sodium
What is first ionization energy?
Sodium's first ionization energy is 495 kJ / mol.
Which is more reactive sodium or barium?
sodium because it's the first group and first group are the most

Sodium
What element in period 3 has the lowest first ionization energy?
Sodium
Does sodium have the larger first ionization energy than potassium?
yes, it does
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. ;)
The amount of energy that is needed to remove the most loosley held electron is referred to as the what?
You are referring to the ionization enthalpy. The first ionization energy of sodium is the energy for the process Na(g) --> Na+(g) + e-(g).
Which element has a lower first ionization energy than element S?
Na, sodium
What is the trend in ionization energy of Na Cl F?
The ionization energy increase from sodium to fluorine.
Which statement describes the general trends in electronegativity and first ionization energy as the elements in Period 3 are considered in order from Na to Cl?
The Pauling electronegativity and the first ionization energy increase from sodium to chlorine.
