Question

Group 18 elements are called _____. (halogens/inert gases)

Answer 1

• Modern periodic table is the arrangement of elements on the basis of increasing atomic number in 7 horizontal rows and 18 vertical columns.
• Horizontal rows are termed as Periods while the vertical columns are termed as Groups.
• Elements present in Group 18 of the periodic table are termed as noble gases or inert gases. It includes Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Ra).
• Due to the presence of a completely filled outermost shell, inert gases have zero tendency to accept or lose any electron. Hence, they are chemically inactive in nature.
• Group 18 elements are called inert gases.
