The innermost electron shell of argon contains 2 electrons, and the outermost shell contains 8 electrons.
To find the answer, we have to know more about the electronic configuration.
What is the electronic configuration of Argon?
- As we know that, the element Argon in the periodic table has an atomic number of 18.
- Since its atomic number is 18, it should have 18 number of electrons in the elemental state.
- The first shell or K shell of Argon can carry 2 electrons, and rest of the 16 electrons will filled in the L and M shells.
- For, L has a maximum number of 8 electrons, and thus, the rest 8 will move to M.
Thus, we can conclude that, the innermost electron shell of argon contains 2 electrons, and the outermost shell contains 8 electrons.
