What is another name for Group 8A?A. Group 18AB. Group 8C. Group 8BD. Group 18

Group 8A in the periodic table is also known as Group 18. This group contains the noble gases, such as helium, neon, argon, krypton, xenon, and radon.

Supplemental Knowledge

The periodic table is an organized arrangement of elements arranged according to their atomic numbers, electron configurations and chemical properties. Groups form vertical columns in this arrangement of the elements with similar chemical behaviors arranged into columns vertically in this diagram. Group 8A or 18 as it's commonly known is made up of noble gases with full valence shell electrons which display minimal chemical reactions when exposed to pressure or chemical attacks.

From Concepts to Reality

Noble gases like helium (He), neon (Ne), and argon (Ar) have practical applications due to their inert nature. For instance:

• Helium is used in balloons and as a cooling medium for superconducting magnets.
• Neon is famous for its use in colorful neon signs.
• Argon is commonly used in welding and as an inert gas shield for arc welding.

These applications emphasize the significance of understanding different groups on the periodic table and their properties.
