In the periodic table, elements are arranged by their atomic number, and they are grouped into regions based on their properties.
- Argon (Ar) is a noble gas found in Group 18 (or Group 0), which is located on the far right side of the periodic table.
- Oxygen (O) is a non-metal located in Group 16 (or Group VI) and is positioned towards the right side, but is not as far right as the noble gases.
- Helium (He) is also a noble gas and is located in Group 18, but it is found at the top of the group, making it the second element from the right.
So to summarize, both Argon and Helium are on the right side of the periodic table, with Argon being further to the right than Oxygen.
