How does mercury differ from other metals?(1 point)
Responses:
It does not chemically react with other elements.
It does not conduct electricity.
It is not solid under normal conditions.
It is not lustrous.
Responses:
It does not chemically react with other elements.
It does not conduct electricity.
It is not solid under normal conditions.
It is not lustrous.
Mercury differs from other metals in that it is not solid under normal conditions. Mercury is a liquid at room temperature, which is unique among metals.
Which statement describes the properties of lanthanoids and actinoids?(1 point)
Responses:
They are malleable and lustrous, and they tend to be poor conductors of both electricity and thermal energy.
They are brittle and dull, and they tend to be poor conductors of both electricity and thermal energy.
They are brittle and dull, and they tend to conduct both electricity and thermal energy.

They are brittle and dull, and they tend to conduct both electricity and thermal energy.
They are malleable and lustrous, and they tend to conduct both electricity and thermal energy.
The correct statement is: They are malleable and lustrous, and they tend to conduct both electricity and thermal energy.
Lanthanoids and actinoids, which are f-block elements, typically exhibit metallic properties such as malleability and lustrous appearance, along with good conductivity of electricity and heat.
