WebAug 15, 2024 · The following equation shows the reaction of hydrogen and oxygen to form hydrogen peroxide: (2) H 2 + O 2 → H 2 O 2. The product of this reaction is called a peroxide because oxygen is in the O 2 2 − form (hydrogen has a +1 oxidation state). This concept is further explained regarding lithium below. WebTo determine the group of p-block elements, the group has to be determined by adding 10 to the total number of electrons in the last orbit. The total number of electrons in the last orbit of the oxygen atom is six. That is, the group number of oxygen is 6 + 10 = 16. Therefore, we can say that the period of the oxygen element is 2 and the group ...
