∙ 9y agoThe horizontal rows in the Periodic Table of elements are called periods. Each period represents a different energy level for the elements.
The horizontal sections of the periodic table are called periods.
The horizontal rows in a periodic table are called periods. Periods represent the number of energy levels an atom's electrons occupy in an element's electron cloud.
Elements to the right of the stair steps on the periodic table are known as nonmetals or metalloids. These elements have properties that are distinct from the metals found on the left side of the stair steps.
The vertical groupings of elements in the periodic table are called "groups" or "families." They share similar chemical properties due to having the same number of electrons in their outer energy level.
The middle block of elements that don't fit in a specific group in the periodic table is known as the transition metals. These elements typically have properties of both metals and nonmetals.
The Periodic Table is arranged like it is for a specific reason. It is probably called the Periodic Table because it is made up of "periods" or horizontal rows.
