(a)
Interpretation:
Among the elements represented by sphere [1], [2] and [3] of the same period, the element with highest
Concept Introduction:
The elements are organized in periodic table on the basis of their electronic configuration. They are put in different groups and periods according to their atomic number. This makes the study of these compounds systematic as elements with same chemical properties fall in the same group.
(b)
Interpretation:
The given elements are represented by sphere [1], [2] and [3] of the same period, the element with largest ionization energy is to be identified.
