it is a diatomic which makes it O2 and it has -2 charge
the symbol for Oxygen is O, the Oxygen ion is 2-. therefore the symbol for the oxygen ion is O2-
Hydrogen + oxygen → water2H2 + O2 → 2H2ORemember to balance the equation
The balanced equation for the decomposition of hydrogen peroxide (H2O2) into water (H2O) and oxygen gas (O2) when heated is: 2 H2O2 (aq) → 2 H2O (l) + O2 (g)
There are two atoms of oxygen on each side.
um, oxygen? The name of the element is the name of... the element. If, i.e., the species you wish to describe is a single atom of neutral oxygen, then it is preferable to call it monatomic oxygen or something for clarity.
O=oxygen atom, o2=oxygen molecule, o2-=oxide, o22-=peroxide, o2-=superoxide, o3=ozone.
O2 represents one molecule . the 2 comes in there to show that 2 atoms come together and make one molecule. one atom of oxygen will be written simply as O
O to the negative 2
the symbol for Oxygen is O, the Oxygen ion is 2-. therefore the symbol for the oxygen ion is O2-
O2- is the oxide ion.
O, O2-, S2-, and Se2-O is smaller than O2- because O2- has 2 extra electrons but the same amount of protons as O, so they are held less tightly and the atom is bigger. Atom size increases as you move down the periodic table, so O2- < S2- < Se2-.
If 2 O is O2: one molecule.
The formula of an oxide is typically written as a combination of the element symbol and the number of oxygen atoms present. For example, the formula for carbon dioxide is CO2, where "C" represents carbon and "O2" represents two oxygen atoms.
The symbol for oxygen, O, does not have a subscript because oxygen is typically found as a diatomic molecule (O2) in nature. The subscript 2 is understood to represent the number of oxygen atoms bonded together.
O2- in oxides, O1- in peroxides
The reduction half-reaction for 2MgO2 to 2MgO is: O2 + 4e- -> 2O2-.
Yes O2 O-O ---------------------------------------- Water is however H20 H-O-H Which is 3 molocules ---------------------------------------
