Electron Arrangements Within Atoms and Subshell Configurations

Practice flashcards covering electron arrangements within atoms, subshell electron capacities, notation components, orbital shapes, and filling order diagrams.

What is the definition of an electron subshell?

A region of space within an electron shell that contains electrons that have the same energy.

According to the subshell table shown, what are the maximum electron capacities for the $s$, $p$, $d$, and $f$ subshells?

The $s$ subshell holds $2$ electrons, $p$ holds $6$, $d$ holds $10$, and $f$ holds $14$.

What is the maximum number of electrons that can be contained in an $s$ subshell?

$2$ electrons.

What is the maximum number of electrons that can be contained in a $p$ subshell?

$6$ electrons.

What is the maximum number of electrons that can be contained in a $d$ subshell?

$10$ electrons.

What is the maximum number of electrons that can be contained in an $f$ subshell?

$14$ electrons.

In the whiteboard diagram shown, what do the label parts (number, letter, and line with arrows) represent in atomic notation?

The number represents the shell, the letter represents the subshell, and the line with arrows represents the orbital.

In electron configuration notation such as $1s$, what does the leading number $1$ represent?

The shell.

In electron configuration notation such as $1s$, what does the letter $s$ represent?

The subshell.

In orbital diagram notation, what does a horizontal line beneath arrows represent?

An orbital.

What are the visual representations for the $s$, $p$, $d$, and $f$ orbitals shown in Figure 3.8?

The $s$ orbital is represented as a single sphere, $p$ orbital as a two-lobed dumbbell, $d$ orbital as a four-lobed structure, and $f$ orbital as an eight-lobed complex structure inside a cube.

What visual shape characterizes an $s$ orbital?

A sphere.

What visual shape characterizes a $p$ orbital?

A dumbbell shape with two lobes.

What does the diagonal arrow diagram represent in electron configuration?

It illustrates the filling order of electron subshells by increasing energy levels.

According to the diagonal filling chart, which subshell is filled immediately after $3p$?

The $4s$ subshell.

According to the diagonal filling chart, which subshell is filled immediately after $4s$?

The $3d$ subshell.

According to the diagonal filling chart, which subshell is filled immediately after $5p$?

The $6s$ subshell.
