Question

where on the periodic table are metalloids found?
the metalloids are in the first two groups of the periodic table.
the metalloids are in the top right part of the periodic table.
the metalloids are in the first two periods of the periodic table.
the metalloids make up the zigzag section that separates the metals and the nonmetals which is found running from boron to astatine.

Explanation:

Metalloids have properties of both metals and non - metals. On the periodic table, they are located in a zig - zag section. This section runs from boron (B) to astatine (At) and separates the metals (on the left) from the non - metals (on the right).
The first two groups (Group 1 and Group 2) are alkali metals and alkaline earth metals (both are metals). The top - right part mainly consists of non - metals. The first two periods contain a mix of metals (e.g., lithium, beryllium) and non - metals (e.g., hydrogen, helium, carbon, nitrogen, oxygen, fluorine).

Answer:

The metalloids make up the zigzag section that separates the metals and the nonmetals which is found running from boron to astatine.
