Air does not have a chemical formula because air is neither an element nor a chemical compound. Air is mixture of Oxygen (element), carbon dioxide (chemical compound), nitrogen (element), and water as humidity (chemical compound).
Air probably does, but you wouldn't write it down. Air is a cocktail of gases and not all of the atoms in air bond, so it is not a compound.
Air is a mixture of several different gases, mostly nitrogen and oxygen. All of the components of air have chemical symbols or formulas. Mixtures don't.
Air is made up of different gasses, so you can't have a formula for air. Gasses like carbon dioxide can have formulas, but just plain air can have carbon dioxide, oxygen, and other gasses
Who told you so: it really has a chemical (elemental) formula He, standing for helium. However it is a noble gas, not capable to ondergo chemical reactions with other elements.
The chemical formula (not symbol) of silicon tetrabromide is SiBr4.
The chemical formula for magnesium is = Mg(OH)2
The answer is PO4
The chemical symbol of lead is Pb - no other formula.
The chemical formula (not symbol) of silicon dioxide is SiO2.
The chemical symbol (not formula) of phosphorous is P; the chemical symbol (not formula) of chlorine is Cl.
The chemical symbol of indium is In.
This gas is argon - 0,9340 %. The chemical symbol (not formula) is Ar.
Free nitrogen is diatomic. Write the formula as: N2.
Chemical symbol is code for a chemical element. Chemical formula is way of expressing information.
The chemical formula (not symbol) is NiBr2.
The chemical formula (not symbol) of sodium sulfide is Na2S.
The chemical symbol (not formula) of indium is In.
With the symbol of a chemical element - of course, if you think to a chemical formula.
The symbol (not chemical formula) for silver is Ag.
The chemical symbol (not formula) of chromium is Cr.
A chemical symbol represents an element. A chemical formula represents a compund. a chemical formula is like this H2O, that is water, a chemical symbol is just this H, that is hydrogen.
