검증된 단계별 안내1
Identify the element in question, which is argon (Ar).
Recall that the periodic table is divided into groups (columns) that categorize elements with similar properties.
Understand that argon is a nonmetal and is chemically inert, meaning it does not easily react with other elements.
Recognize that elements with these properties belong to the group called noble gases, which is Group 18 on the periodic table.
Therefore, argon (Ar) belongs to the Noble gases group, Group 18.
