Metalloids or semiconductors
Idk
The metalloids are found bordering the stair-step line, except for Aluminium and Astatine. The stair-step line divides the metals and non-metals and is near the right side of the table.
The metals and non-metals are separated by a "stair-step" pattern that begins between polonium and astatine and moves up/left to boron. Most periodic tables display this stair-step as a bold line, or a different color, or something else easy to spot. Generally speaking, the metals are everything to the left of the stair-step, and the non-metals are everything to the right. The small handful of elements that "ride" the stair-step are called metalloids. Metalloids can have properties of both metals and non-metals.
Waka flacka. you do not step on the riser
You must mean a stair "tread": the horizontal board, or structural member - of whatever material - that you step on climbing a stairway; a good carpentry book will advise you how to construct them.
metal, metalloid, and non-metal. Metals are everything left of the stair-step line, metalloids are MOST of the metals along the stair-step line, and non-metals are everything to the right of that line. The stair-step line is a line that goes (in a stair-like fashion) from between Al and B to between Po and At.

This is a colloquial North of England expression. Stair-rods are the metal rods that hold stair-carpets in place on each step. The allusion is to rain which is so heavy as to appear like falling stair-rods.
here you need to know they are like elevating stair or elevators
What you do to tea is to stir it with a spoon. (stur)The homophones are stare (look) and stair (a step up), both pronounced (stayr).
If the stair step line on Periodic Table divide, then the elements to the left of this line are metals, except hydrogen

The elements on the stair step line are metalloids, to its left are metals and to its right are non metals.
