patterns formed in columns and rows.
question 2

Explanation:

When scientists grouped elements by similar properties, they noticed patterns formed in columns and rows. This is a fundamental aspect of the periodic table. Elements in the same column (group) have similar chemical properties, and elements in the same row (period) show trends in properties. The other options are incorrect: elements don't disappear when grouped, gases aren't all at the bottom, and the table isn't circular.

Answer:

Patterns formed in columns and rows.
