Concept explainers
(a)
Interpretation:
The reason as to why the first ionization energy of potassium is less than that of sodium is to be stated.
Concept introduction:
Ionization energy is defined as the minimum amount of energy that is required to completely remove an electron from an atom or ion in its gaseous state. It is calculated by subtracting the energy of the neutral atom from the energy of the ion formed.
(b)
Interpretation:
The reason as to why the first ionization energy of chlorine is greater than that of sulfur is to be stated.
Concept introduction:
Ionization energy is defined as the minimum amount of energy that is required to completely remove an electron from an atom or ion in its gaseous state. It is calculated by subtracting the energy of the neutral atom from the energy of the ion formed.
