Question

1. choose the best answer. which element group conducts heat and electricity and can be stretched and shaped? nonmetals lanthanides metals metalloids 9. choose the best answer. combining substances physically results in a ____. mixture solid transition metal molecule

Explanation:

• Metals are known for their ability to conduct heat and electricity, and they are malleable (can be shaped) and ductile (can be stretched). Non - metals generally do not have these properties. Lanthanides are a specific group of metals but are not the most general answer. Metalloids have some properties of both metals and non - metals but are not as good conductors or as malleable/ductile as metals.
• When substances are combined physically, the result is a mixture. A solid is a state of matter, not the result of a physical combination. A transition metal is a type of metal and not related to physical combination. A molecule is formed by chemical bonding, not just physical combination.

Answer:

1. C. metals
2. A. mixture
