Concept explainers
(a)
Interpretation:
The changes in size from potassium to calcium have to be determined.
Concept Introduction:
Atomic size is half of the distance between the adjacent atoms in the molecule. Since the electron cloud has no fixed boundary so the size of the atom is measured with high difficulty.
(b)
Interpretation:
The changes in ionization energy from potassium to calcium have to be determined.
Concept Introduction:
The energy that is needed to remove an electron from the isolated, neutral gaseous atom is known as ionization energy. It is represented by
(c)
Interpretation:
The changes in
Concept Introduction:
The change in energy when an electron is added to the neutral gaseous atom is known as electron affinity. An anion is formed in this process.
