patterns formed in columns and rows. question 2 why are metalloids shown in a \stair - step\ zone on the periodic table? they share properties with both metals and nonmetals. they are used for ride safety. they are gases and solids. they are decorative elements. question 3 why do engineers use different types of

Explanation:

Metalloids have properties intermediate between metals and non - metals. The "stair - step" zone in the periodic table separates metals from non - metals. Since metalloids share properties with both, they are placed in this transitional zone. The other options are incorrect: "used for ride safety" is not a relevant property for their placement in the periodic table; not all metalloids are gases and solids (most are solids); and they are not primarily decorative elements.

Answer:

They share properties with both metals and nonmetals.
