reaction of non metals with oxygen class 8

But all metals do not react in the same way with water. The physical properties are insufficient to identify if a substance is metal or a nonmetal and so there is need to test chemical properties of metal and non-metal . Which of the following statements is correct? Lesson: Lesson 4: Reacting metals and non-metals with Oxygen. Lets start with reaction of metals with oxygen.
