The noble gas element in the given options is radon (Rn).
The noble gas element among the given options is radon (Rn).
To identify the noble gas element, you can refer to the periodic table. Noble gases are located in Group 18 of the periodic table, also known as the "noble gases group" or "Group 18 elements." These gases are known for their low reactivity and full outer electron shells, which make them stable.
From the provided options, hydrogen (H), rubidium (Rb), and fluorine (F) are not noble gases. Hydrogen is found in Group 1 and is not a noble gas. Rubidium is in Group 1 as well and is an alkali metal. Fluorine is in Group 17 and is a halogen.
Therefore, the correct answer is radon (Rn), which is a noble gas.
