A
Magnesium (Mg)
B
Argon (Ar)
C
Chlorine (Cl)
D
Sodium (Na)
Verified step by step guidance
1
Identify the group (column) in the periodic table where neon (Ne) is located. Neon is a noble gas, which means it is in Group 18 (also called Group 8A or the noble gases group).
Recall that elements in the same group have similar chemical properties because they have the same number of valence electrons.
Check the given options and determine which element is also in Group 18. Argon (Ar) is in Group 18, just like neon, while magnesium (Mg), chlorine (Cl), and sodium (Na) belong to different groups.
Understand that since argon and neon are both noble gases, they share similar properties such as being inert and having full valence electron shells.
Conclude that the element with properties most similar to neon is argon (Ar) because it is in the same group on the periodic table.
