Question

which element group conducts heat and electricity and can be stretched and shaped? nonmetals metalloids lanthanides metals

Explanation:

Metals are known for their ability to conduct heat and electricity well. They are also malleable (can be shaped) and ductile (can be stretched). Non - metals generally do not conduct heat and electricity as effectively and are not malleable or ductile. Metalloids have some properties of both metals and non - metals but not as pronounced in conductivity, malleability, and ductility as metals. Lanthanides are a specific group of metals but the general property of conducting heat/electricity and being stretchable and shapable is characteristic of metals in general.

Answer:

D. metals
