Atomic Number of Argon is 18.
Argon has an atomic number of 18 and and Atomic mass of 40. How many protons, neutrons and electrons does Argon have? 18 protons, 18 electrons, 40-18=22 neutrons. Atomic Number of Argon Argon is a chemical element with atomic number 18 which means there are 18 protons and 18 electrons in the atomic structure. The chemical symbol for Argon is Ar. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. 2020-11-21 by Nick Connor Atomic Mass of Argon Atomic mass of Argon is 39.948 u. How to Write the Electron Configuration for Argon (Ar) In order to write the Argon electron configuration we first need to know the number of electrons for the Ar atom (there are 18 electrons). When we write the configuration we'll put all 18 electrons in orbitals around the nucleus of the Argon atom.
Chemical symbol for Argon is Ar. Number of protons in Argon is 18. Atomic weight of Argon is 39.948 u or g/mol. Melting point of Argon is -189,4 °C and its the boiling point is -185,9 °C.

Argon is a gas without color and odor, which is one of the noble gases and is totally not reactive with other elements of the Periodic Table. The name of this chemical element originates from the Greek word meaning idle. There is some argon in its pure form in the atmosphere of our planet (estimated to be a little less than 1 per cent) but it has no high biological importance. Argon turns light violet when electricity passes through it. It is used in welding as well as in light and fluorescent bulbs. Also, argon is used to fill up space between two panes of the double glazed windows.
Uses of Argon
Argon, inert gas with the symbol Ar, is used in radio tubes, Geiger counters, fluorescent tubes, and incandescent light bulbs. It is also used in double-glazed windows to fill the space between the panes. And it is used in the production of some metals like titanium, uranium, and zirconium.
Argon can be used in neon lights, heat-treating processes, scientific research, medicine, and 3-D printing too.
