One. The II in Iron II means that the ion has a 2+ charge. Oxygen atoms, when they are not bonded to any other atoms (include another oxygen) have a 2- charge. So, when the 2+ and the 2- react, they form a very stable bond.
Here's the reaction.
Fe2+ + O2- --> FeO
The two atoms that combine are a metal atom and an oxygen atom.
Two atoms of lithium will combine with three atoms of oxygen to form lithium oxide, with the chemical formula Li2O. Each lithium atom can donate one electron to each oxygen atom, resulting in a stable compound.
Nitrous oxide, commonly known as laughing gas, is a chemical compound with the formula N2O, so it consists of TWO elements: Nitrogen (2 atoms) and Oxygen (1 atom), which are together three ATOMS.
In sodium oxide, there are two kinds of atoms: sodium (Na) and oxygen (O). Sodium is a metal while oxygen is a non-metal. They combine to form the compound sodium oxide with the chemical formula Na2O.
Magnesium and oxygen combine to form magnesium oxide. It is basic in nature.

Lead and oxygen combine to form lead oxide (PbO).
No, when 100g of iron reacts with oxygen to form iron oxide, the resulting compound will have a different mass than the initial iron due to the addition of oxygen atoms. The mass of the iron oxide formed will be greater than 100g, as the oxygen atoms combine with the iron atoms to form the compound.
In sodium oxide, there are two kinds of atoms: sodium (Na) and oxygen (O). Sodium is a metal while oxygen is a non-metal. They combine to form the compound sodium oxide with the chemical formula Na2O.
Magnesium and oxygen combine to form magnesium oxide. It is basic in nature.
When magnesium reacts with oxygen to form magnesium oxide, the magnesium atoms lose electrons to form magnesium ions, and oxygen atoms gain electrons to form oxide ions. The magnesium ions and oxide ions then combine through ionic bonding to form the compound magnesium oxide.
reactants: iron and oxygen products: rust (aka: iron (II) oxide or FeO)
When magnesium is burned in oxygen, it undergoes a chemical reaction called combustion. During this reaction, magnesium atoms combine with oxygen atoms to form magnesium oxide. The increased mass observed after burning magnesium is due to the formation of magnesium oxide, which adds the combined mass of magnesium and oxygen atoms to the initial mass of the magnesium.
The formula of the product would be sodium oxide (Na2O). Sodium metal reacts with oxygen gas to form sodium oxide, where two sodium atoms combine with one oxygen atom.
Sodium combines with oxygen in a 2:1 ratio to form sodium oxide (Na2O). Two atoms of sodium combine with one atom of oxygen to create a stable compound.
