The pin index safety system uses a face seal between the cylinder valve and the associated yoke clamp. There are two holes in specific positions on the cylinder valve body below the outlet port , in positions associated with the gas mixture, which prevent connection of the cylinder to a yoke or pressure regulator with a mis-matched set of pins. The holes accept pins 4 mm diameter by 6 mm long which are correctly aligned with the holes. Web29 dec. 2024 · Now, Oxygen has an atomic number of 8 and it contains a total number of 8 electrons. Hence, 2 electrons will go in the first shell (K) and 6 electrons will go in the second shell (L). Therefore, the electrons per shell for Oxygen is 2, 6, hence, we can say, based on the shell, the electronic configuration of the Oxygen atom is [2, 6].
