They are 'inert' elements, and gases too.
Helium, argon, and neon are noble gases with different atomic numbers: helium (2), neon (10), and argon (18). They vary in terms of their densities, boiling points, and chemical reactivity. Neon has the lowest boiling point and argon has the highest atomic weight among the three.
When neon, argon, and helium are combined, they form a mixture of noble gases. These gases are colorless, odorless, and generally inert. The resulting mixture would not undergo any chemical reactions with each other.
The outer electron orbits of helium, neon, and argon are all filled with electrons, making them stable and inert. This results in these elements having very low reactivity and being part of the noble gases group on the periodic table. Helium has 2 electrons in its outer orbit, neon has 8, and argon has 18.
Helium and neon do not typically react with iron under normal conditions. Argon is inert and does not chemically react with iron.
Yes, argon is commonly used in neon lights along with a small amount of neon gas. When an electric current passes through the argon and neon gases inside the tube, it excites their atoms and produces the characteristic bright glow associated with neon lights.
Helium, neon, argon are used because they are chemically inactive.
Helium, neon, and argon are the three lightest members of the noble gases.
The first four are (in order of increasing number / mass: He = Helium, Ne = Neon, Ar = Argon, Kr = Krypton Xe = Xenon and Ra = Radon are the other two noble gases
Noble gases
They are all gases.
All of the group 8 (group 0) elements - Helium, Neon, Argon, Krypton, Xenon, Radon
There are 6 noble gases: helium, neon, argon, krypton, argon and radon
HELIUM,NEON,ARGON,KRYPTON,XENON and RADON are the noble gases
Inactive gases are gases that are chemically unreactive under normal conditions. They often include noble gases such as helium, neon, argon, krypton, xenon, and radon. These gases have a stable electron configuration and are generally non-reactive with other elements.
