(b)[2 marks]Which one element forms an acidic oxide? Explain your answer.
(c)[1 mark]State one property (other than oxide character) that most metals have which non-metals do not.
Question 18
2 marks · Hard
Answer and see the solution →Give a reason why elements in Group 0 (the noble gases) do not easily form compounds. Your answer should refer to their electronic structure.
