two representations of the distribution of electrons in the potassium atom are shown. model 1 1s²2s²2p⁶3s²3p⁶4s¹ 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.

two representations of the distribution of electrons in the potassium atom are shown. model 1 1s²2s²2p⁶3s²3p⁶4s¹ 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.

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 and indicates the single electron in the 4s (outermost) orbital. Model 2 is a Bohr - type model showing the single electron in the outermost ring. Both models convey the presence of a single outer - shell electron which is responsible for potassium's reactivity.

Answer:

Both models because each shows an electron in the outermost shell.
