(a)
Answer to Problem 16PEB
Solution:
The charge on the ion of Aluminum is
Explanation of Solution
Introduction:
The charge on an ion is equal to the valency of an atom and positive charge represents the loss of electron by an atom while negative charge represents the gain of electron by an atom. Elements which have one, two, or three outer electrons tends to lose these electrons to form positive ions. Similarly, elements which have five to seven outer electronstends to gainelectrons to complete their outer orbitals.

(The answer cannot be found on the other choices.) b. For materials with fewer than three valence electrons, less or insignificant electric field is produced in the conductor. This is the reason why the electric field inside a conductor is zero. c. Originally, these materials have eight valence electrons. Greater than four of these valence electrons became free electrons and fewer than four valence electrons remained. This is why conductors have more free electrons at room temperature. d. Valence electrons in these materials need less energy gap is needed to be overcame to dislodge them from their parent atoms to become free electrons. Hence, conductors have overlapping conduction and valence bands.arrow_forward
