two representations of the distribution of electrons in the potassium atom are shown.
model 1
$1s^22s^22p^63s^23p^64s^1$
model 2
which model is useful in showing the reactivity of potassium?
○ neither model is able to show the reactivity of potassium.
○ model 1 because it shows an electron in the 4s orbital.
○ model 2 because it shows an electron in the outermost ring.
○ both models because each shows an electron in the outermost shell.

Explanation:

that drive reactivity. While Model 1 includes the 4s¹ electron, its condensed notation is less intuitive for visualizing the outermost shell's role in reactivity compared to the shell diagram in Model 2.
