Which gases are elements?
Some gases that are elements include oxygen (O), nitrogen (N), hydrogen (H), helium (He), neon (Ne), and argon (Ar). These gases exist as individual atoms and are considered elements on the periodic table.
What is colder helium or hydrogen?
Liquid Helium is colder than Liquid Hydrogen.
What were the first four elements used in chemistry?
If you mean the elements that are gases at standard temperature and pressure the the first four gases to be discovered are: hydrogen (H) was discovered by Henry Cavendish in 1766; nitrogen (N) was discovered by Daniel Rutherford in 1772; oxygen (O) was discovered by Joseph Priestly in 1774; and chlorine (Cl) was discovered by Carl Wilhelm Scheele in 1774.
How many atoms are in a molecule of hydrogen?
There are two hydrogen atoms in a hydrogen molecule. It is a diatomic molecule, meaning that there is two atoms in one molecule. Many gases are diatomic. In the Periodic Table there are 11 elements that are gases at Room Temperature: Hydrogen, Helium, Nitrogen, Oxygen, Fluorine, Neon, Chlorine, Argon, Krypton, Xenon and Radon. Of these gases, the ones that are diatomic are: Hydrogen, Nitrogen, Oxygen, Fluorine and Chlorine. One liquid and two solids are also diatomic, the liquid: Bromine, the solids: Iodine and Astatine.
What is the composition of the planet Jupiter?
Jupiter is composed of mostly liquid metallic Hydrogen, some Helium, and molecular Hydrogen. There are thought to be a mixture of elements in the core.
