two representations of the distribution of electrons in the potassium atom are shown.\nmodel 1\n1s²2s²2p⁶3s²3p⁶4s¹\nmodel 2\nwhich model is useful in showing the reactivity of potassium?\nneither model is able to show the reactivity of potassium.\nmodel 1 because it shows an electron in the 4s orbital.\nmodel 2 because it shows an electron in the outermost ring.\nboth models because each shows an electron in the outermost shell.
Answer
Brief Explanations:
The reactivity of an atom is related to the number of electrons in its outermost shell. Model 1 shows the electron - configuration with the outermost electron in the 4s orbital, and Model 2 shows the outermost electron in the outermost ring. Both indicate the single outermost electron which is responsible for potassium's reactivity.
Answer:
D. Both models because each shows an electron in the outermost shell.
