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 element in period 3 has the lowest first ionization energy?
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.
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
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.
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?
