Argon is most the most abundant Rare Gas in the atmosphere. Its elemental symbol is Ar. 

Round-robin (RR) is one of the algorithms employed by process and network schedulers in computing.

According to Bohr model, Each shell can occupy 2n2 electrons in their orbits where n=1,2,3.. for K,L,M,..

The atom has 2 electrons in k, 8 electrons in L and 7 electrons in M = 2 + 8 + 7 = 17

And given that its nucleus has 18 neutrons

=> its mass number = number of (electrons + neutrons ) = 17 + 18 = 35
