Question

question 4 of 10 which of the following elements shows little reactivity? a. sulfur (s) b. argon (ar) c. fluorine (f) d. potassium (k)

Explanation:

Argon is a noble - gas. Noble gases have a full outer electron shell, which makes them very stable and less likely to react with other substances. Sulfur is a non - metal and can form compounds easily. Fluorine is a highly reactive non - metal due to its strong tendency to gain an electron. Potassium is a highly reactive metal as it readily loses its outer electron.

Answer:

B. Argon (Ar)
