well Mg is an element ( I Magnesium) and O is oxygen hence MgO is definitely a molecule not an atom ...
== == MgO That would be Magnesium rust. It makes Magnesium off color and cloudy.
Magnesium oxide is represented as MgO, not 2Mg O2. Mg represents one magnesium atom, and O represents one oxygen atom. When these two elements react, they form one molecule of magnesium oxide, which is composed of one magnesium atom and one oxygen atom.
the final formula of magnesium oxide is MgO.
it is soluble (sulphates get less soluble as you go down the group in the periodic table)
A molecule.
One formula unit of MgO contains one atom of magnesium and one atom of oxygen, so the total number of atoms in MgO is 2.
The molecule that contains a covalent bond is CN- (cyanide). MgO is an ionic compound, HF is a polar covalent molecule, and HCl is also a polar covalent molecule.

One molecule of oxygen will react with one molecule of hydrogen to produce one molecule of hydrogen peroxide: H2 + O2 --> H2O2 One half molecule of oxygen will react with one molecule of hydrogen to produce one molecule of water: H2 + ½O2 --> H2O ...but nobody would write it like that. It is more correct as follows: 2H2 + O2 --> 2H2O
Is Ne a atom or molecule
no an atom is a part of a molecule.
A carbohydrate is a molecule, not an atom.
the final formula of magnesium oxide is MgO.
The percent composition of magnesium (Mg) in MgO is 60%. This is because there is one magnesium atom (24.3 g/mol) and one oxygen atom (16.0 g/mol) in the formula unit MgO (40.3 g/mol), so dividing the molar mass of magnesium by the molar mass of MgO gives 0.603, or 60.3%.

O is an atom, but O2 is a molecule.
