(a)
Interpretation: The no. of electrons in the 2p sub-level of aluminum is to be determined.
Concept introduction:
The electron configuration of an element defines how its electrons are arranged throughout its atomic orbitals. Standard notation is used to represent atomic electron configurations, placing all electron-containing atomic subshells in sequential order. The number of electrons held by the subshell is indicated by superscript.
(a)
Answer to Problem 102A
6
Explanation of Solution
Thus, no. of electrons in the 2p sublevel is 6.
(b)
Interpretation: The no. of electrons in the 2p sub-level of carbon is to be determined.

(b)
Answer to Problem 102A
2
Explanation of Solution
Atomic number of carbon is 6 and its electronic configuration is as follows:
Thus, no. of electrons in the 2p sublevel is 2.
(c)
Interpretation: The no. of electrons in the 2p sub-level of fluorine is to be determined.

(c)
Answer to Problem 102A
5
Explanation of Solution
Atomic number of fluorine is 9 and its electronic configuration is as follows:
Thus, no. of electrons in the 2p sublevel is 5.
(d)
Interpretation: The no. of electrons in the 2p sub-level of lithium is to be determined.

(d)
Answer to Problem 102A
0
Explanation of Solution
Atomic number of lithium is 3 and its electronic configuration is as follows:
Thus, no. of electrons in the 2p sublevel is 0.
