Concept explainers
(a)
Interpretation:
The orbital diagram (a) is correct or incorrect have to be identified
Concept Introduction:
Aufbau’s principle:
Aufbau’s principle states that electrons are filled into atomic orbitals in the increasing order of orbital energy level. According to the Aufbau principle the available atomic orbitals with the lowest energy levels are occupied before those with higher energy levels.
Figure 1
Hund’s Rule:
According to Hund’s rule every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied and all electrons in singly occupied orbitals have the same spin.
(b)
Interpretation:
The orbital diagram (b) is correct or incorrect have to be identified.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
The orbital diagram (c) is correct or incorrect have to be identified.
Concept Introduction:
Refer to part (a).
(d)
Interpretation:
The orbital diagram (d) is correct or incorrect have to be identified.
Concept Introduction:
Refer to part (a).
