If the stair step line on Periodic Table divide, then the elements to the left of this line are metals, except hydrogen
The stair step line
those to the right of the stair-step line
Metalloids or semiconductors
Another name for stair case on periodic table is Metalloids.
Al is a transitional metal since it is under the stair-step line that divides transitional metals from non-metals.
Divides metals and non metals
The elements on the stair step line are metalloids, to its left are metals and to its right are non metals.
The elements on the stair step line are metalloids, to its left are metals and to its right are non metals.
Elements that lie along the stair-step line of the periodic table, known as metalloids, can be solid, liquid, or gas at room temperature depending on the specific element. For example, arsenic and antimony are metalloids that are solid at room temperature, while mercury, also a metalloid, is a liquid at room temperature.
The elements along the stair-step line on the periodic table are known as metalloids. These elements exhibit properties of both metals and nonmetals, making them unique in their behavior and applications. Common examples of metalloids include silicon, germanium, and arsenic. They are often used in semiconductors and various industrial applications.
The bold, stair-step black line on the periodic table represents the division between metals and nonmetals. Elements to the left of the line are metals, while elements to the right are nonmetals. Elements along the line are metalloids, which have properties of both metals and nonmetals.
Metalloids can be found along the diagonal line between metals and nonmetals on the periodic table. They include elements such as boron, silicon, germanium, arsenic, antimony, and tellurium. Metalloids exhibit properties that are intermediate between metals and nonmetals.
