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.
