Neon!
Helium!
The second lightest element on the periodic table is Helium (He). The easiest way to tell this is by the numbers on the periodic table, all elements are in atomic weight order (super-light gases to super-heavy elements).
Hydrogen and helium. It's better to ask which two ELEMENTS make up the bulk of the stars, since ALL elements in a star are in the gaseous state.
Type of gaseous waste
They are elements that are in the gas phase under normal temperature and pressure (1 atmosphere of pressure at 273 K). The gaseous elements are: hydrogen (H2), helium (He), nitrogen (N2), oxygen (O2), fluorine (F2), neon (Ne), chlorine (Cl), argon (Ar), kyrpton (Kr), xenon (Xe) and radon (Rn). Note that some are diatomics and are composed of two of the same atom, while the others are not -- the ones that are not diatomics are all noble gasses
Gaseous exchange is a natural process, ventilation is a forced process.
Neon!
Hydrogen
A colorless, odorless, highly unreactive gaseous element. Xenon and similar elements are called Noble Gases
hydrogen
Hydrogen is H2, a diatomic gaseous element
Hydrogen is an element on the periodic table. Hydrogen is a brinclhof element (Br, I, N, Cl, H, O, F) and as such occurs in pairs (H subscript 2) in its gaseous state.
No, it is a colorless, highly flammable gaseous element, the lightest of all gases and the most abundant element in the universe.
in the air we breath, 2/3 are nitrogen and 1/3 is oxygen. there are traces of other gases
NO!!! Potassium hydroxide contains;- 1 X potassium(K) 1 x Oxygen (O) 1 x Hydrogen (H). To give the formula 'KOH'. NB Helium is 'He'. It is the most unreactive element of all. It remains in the monatomic gaseous state. So it is not part of potassium hydroxide.
No it would be a group 18 element (helium, neon, argon, xenom, krypton or radon). These are unreactive, gaseous non-metals, which don't conduct heat or electricity at all well.
The gaseous product in this reaction is 'hydrogen' and the salt is zinc sulfate.
Radon is the densest gaseous element.
