Question

ionization energy is the amount of energy required to remove one electron from ca(s) and form ca+(g)

Explanation:

Ionization energy is the energy required to remove an electron from a gaseous atom or ion. The correct definition for the first - ionization energy of calcium would be the energy required to remove one electron from a gaseous calcium atom ($Ca(g)$) to form a gaseous calcium ion with a + 1 charge ($Ca^{+}(g)$), not from the solid calcium ($Ca(s)$).

Answer:

False
