(a)
Interpretation:
The elements that are diamagnetic in the first transition series has to be identified.
Concept Introduction:
Diamagnetic: When atoms or ions with all electrons are paired their magnetic field effectively cancels each other. Substances with paired electrons are called diamagnetic. They are weakly repelled by magnetic fields.
Paramagnetic: Atoms or ions with unpaired electrons are attracted to magnetic field. Substances with unpaired electrons are called paramagnetic.
(b)
Interpretation:
Among the elements in first transition series, the element with greatest number of unpaired electrons has to be identified.

- Which element is a main-group metal? (a) O (b) Ag (c) P (d) Pbarrow_forward(1) The element with a valence electron configuration of 2s is in group and period (2) The element with a valence electron configuration of 4s is in group and periodarrow_forwardElements can be classified into groups based on their electron configurations. The representative elements are those that have s and p orbitals. The transition elements are elements that fill the d orbitals (groups 3–11 on the periodic table), and the inner transition metals are elements that fill the f orbitals.
