Question: Where do the gaseous elements tend to be located on the table?

Expert Verified Solution:

Gaseous elements on the periodic table are primarily located in two distinct regions: the far right side and the top of the periodic table. The gaseous elements tend to be in the noble gases group (Group 18) and the nonmetals on the upper right side of the periodic table.

Noble Gases: The noble gases, which include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn), are found in Group 18. These gases are characterized by their full valence electron shells, making them chemically inert and generally nonreactive.

Nonmetals: Additionally, other gaseous elements such as hydrogen (H), nitrogen (N), oxygen (O), fluorine (F), and chlorine (Cl) are located in the upper right part of the periodic table. These elements are typically nonmetals and can form various types of bonds and compounds.

The positioning of these gaseous elements reflects their unique chemical properties, including their tendencies to exist as gases under standard conditions. For instance, hydrogen is the lightest and most abundant element in the universe, while nitrogen and oxygen are essential components of Earth’s atmosphere.

Thus, gaseous elements tend to be located on the far right side and the upper part of the periodic table, where they exhibit their characteristic properties of low boiling points and high volatility.
