Guida verificata passo dopo passo1
Understand that the noble gases are elements located in Group 18 of the periodic table. These elements are known for their full outer electron shells, making them very stable and mostly inert.
Recall the common elements in Group 18: Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).
Look at the given options: Sodium (Na), Chlorine (Cl), Neon (Ne), and Magnesium (Mg).
Identify the position of each element on the periodic table: Sodium is in Group 1, Chlorine is in Group 17, Neon is in Group 18, and Magnesium is in Group 2.
Conclude that Neon (Ne) is the element that belongs to the noble gas family (Group 18) because it is located in that group on the periodic table.
