The weight of an argon atom is approximately 39.95 atomic mass units, which is equivalent to 6.63 x 10^-26 kg.
The atomic weight of argon is approximately 39.95 atomic mass units.
39.948 is the atomic weight of Argon. I hope this helps!
argon is one of rare gases its atomic weight is 39.948 and atomic number is 18
The number of neutrons in an atom of argon is typically 22. Argon has an atomic number of 18, which means it has 18 protons in its nucleus. The number of neutrons is calculated by subtracting the atomic number from the atomic mass, which is approximately 40 for argon.
39.948
The standard atomic notation for an atom of argon with 20 neutrons and 18 protons is 38Ar.
Yes. Because argon is an element the smallest "piece" of it is referred to as an atom.
In any neutral atom, the number of electrons is the same as the number of protons, and that is defined as the atomic number of the atom. The atomic number of argon is 18; therefore, each atom contains 18 electrons.
