The electron configuration for aluminum (Al) is shown below:1s22s22p63s23p1Which diagram shows the correct distribution of electrons in the electron shells of an aluminum atom?
Type in your answer below.
Dot structures make it easy to count electrons in each shell. Arrow-and-line diagrams show every orbital and the spin of electrons. Written configurations use minimal space and show how electrons are distributed among subshells.
Did your answer include at least one of the items listed in each category below?
What rule/principle states that electrons fill orbitals from lowest energy to highest energy?
Which diagram shows the correct electron configuration for fluorine (F)?
What rule/principle states that electrons in the same sublevel (p, d, or f) are placed in individual orbitals, before they are paired up, to increase atomic stability?
