What is the term for the arrangement of elements in columns with repeating properties?

• A. Periodic table
• B. Group
• C. Period
• D. Crust

Answer: (A)

Elements are organized in a table where elements with similar properties sit in the same vertical column, and their patterns repeat across the table. This overall arrangement is called the periodic table. The idea is that elements in the same column (a group) share similar chemical behavior, and the table as a whole shows periodic repetition of properties as you move through periods and groups. A group is just one column, not the whole arrangement. A period is a horizontal row, not columns. Crust isn’t relevant here.
