Ar
Argon is a non metal element. Atomic mass of it is 39.94.
It is 87.3 K.
There are three natural isotopes.
argon's atomic number is 18
All I know is that it's nearly 20
Helium, Xenon, Neon, Krypton, and Radon.
Argon is a noble gas and so is inert. Its name derives from the Greek word αργον, meaning "lazy" or "inactive". This refers to the fact that argon takes part in almost no chemical reactions.
For most people there is absolutely no reason to buy any argon in their lifetimes.
Since Argon is normally a gas, it would not be thought of as having any texture.
Argon is very unreactive as it is a noble gas. Its common oxidation number is zero.
Argon atoms have 18 protons which is similar to the number of electrons.
