Passage VI
An atomic orbital can contain 0, 1, or 2 electrons. It is filled when it contains 2 electrons. An orbital's location and shape are determined by its energy level and sublevel. Table 1 lists the first 4 energy levels, their sublevels, and the number of orbitals in each sublevel.
Table 2 names each of the sublevels in the first 4 energy levels.
Table 3 shows the order in which the sublevels are filled with electrons. Each sublevel must be filled before an electron can be added to the next sublevel.
Tables 4 illustrates a notation used to indicate the number of electrons per sublevel.

30. Based on Table 4, which of the following notations indicates an atom that has exactly 11 electrons?
Your Answer is
Correct Answer is G
Explanation
According to table 4, it can be learned that all the superscripts represent the number of electrons, so the F option has a total of 2+2+6=10 electrons, which are excluded;
The G option has a total of 2+2+6+ electrons 1=11, correct
