Concept explainers
(a)
Interpretation:
The complete electronic configuration of antimony has to be given.
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
(b)
Interpretation:
The shorthand electronic configuration of antimony has to be given.
(c)
Interpretation:
The number of valence electrons in antimony has to be given.
Concept Introduction:
Valence electrons:
Valence shell is the outermost shell of an every element. Atom of every element has different electronic configurations based on the atomic number of each element. Valence electrons are those electrons that located in the outermost shell surrounding an atomic nucleus.
Example: Sodium
The atomic number of sodium is
The electronic configuration of sodium is
The outermost shell (valence shell) is
The valence electron is one.
(d)
Interpretation:
The valence electrons in the shorthand electronic configuration have to be underlined.
