Nitrogen, Oxygen and Hydrogen. There are also small traces of Neon and Helium. I don't know if those are considered trace elements or not but I hope that helps. :)
Xenon, helium, and krypton are trace elements in air.
The trace elements in air are: Argon, Neon, Hydrogen, Sulfur and Krypton.
There are possibly more, however it would be in such low quantise we couldn't properly measure it.
Tiny amounts of minerals are called 'trace' amounts.
Al, Si
Air contains approximately 78% nitrogen, 21% oxygen and the final 1% is made up of argon, carbon dioxide and trace amounts of other gases. There is a possibility that air could also contain many bacteria and viruses from humans sneezing.
Water is composed of two elements - Oxygen and Hydrogen. Air is composed of individual elements (mainly Oxygen & Nitrogen and other trace gasses) in individual atoms.
The main elements found in teeth are calcium, phosphorus, and trace amounts of other minerals such as fluoride, potassium, and sodium.
Earth, air, fire, and water.

Air is not an element, but made of elements. Mostly nitrogen and oxygen, with helium, hydrogen and other trace elements.
The air we breath is a mixture on (in Order) Nitrogen, oxegen, and many many trace elements.
Trace Element
Nitrogen, oxygen carbon-dioxide, trace amounts of helium and other compounds.
heavy metals are natural elements and are found in trace amounts everywhere and in everything. the problem is when they accumulate to more then trace amounts.
The trace elements in concrete are,CementFine aggregateCoarse aggregateWaterAdmixtures.
A1. Air is neither a solution nor a compound. It is a mixture from which the individual components are easily separated.A2. I would really call it more of a compound. It's a mix of many different elements like oxygen or nitrogen. There are also many elements found in trace amounts.
