(a)
Interpretation:
Which element is a metal should be determined.
Concept introduction:
Most of the elements found in the periodic table are metals. All elements in group 1 and 2 are metals except hydrogen. All elements in d block are metals. They are called
(b)
Interpretation:
Which element has the greater ionization energy should be determined.
Concept introduction:
Ionization energy is amount of energy must be absorbed by a gaseous atom in ground state to remove an electron. Further away the electron from the nucleus; it’s easy to remove the electron from the atom/ion. Hence, ionization energy will be less.
(c)
Interpretation:
Which element has the larger atomic radius should be determined.
Concept introduction:
Atomic radius is the distance between the nucleus and the valence electron shell of the atom.
(d)
Interpretation:
Which element has the greater
Concept introduction:
Electron affinity is the change in energy when an electron is added to an atom to form a negative ion.
