Bromine, as the element is called on its own is a nonmetal, and is a poor conductor of electricity. Bromide salts conduct electricity if dissolved in water or molten, but not in their normal solid states.
No solid iodine does not conduct electricity.
Gold, silver, copper.
A gas is usually a poor conductor of electricity. In contrast, a brittle solid material that is a poor conductor of electricity is typically an insulator.
A substance that conducts electricity is a conductor. There is no special name for one that is solid; if you need to specify that it is solid, just call it a "solid conductor".
Any of the ceramic like materials. Look to the up and to the right of the periodic table. Semi-metals and solid non metals would be good places to start.
The element that fits all of these characteristics is sulfur. Sulfur is a non-metal that is a poor conductor of electricity, has a yellow color, is brittle in its solid form, is not magnetic, and is not ductile. Additionally, sulfur exists as a solid at room temperature.
Glass in its solid state is an insulator of electricity.
No solid iodine does not conduct electricity.
Glass in a molten state is a conductor of electricity. When glass turns to a solid state it becomes an insulator.Basically, glass in a window or a test tube would be the solid state and so it is a insulator of electricity.
Iodine, either in its solid state or dissolved in alcohol, is not a conductor of electricity.
To figure this out, we need to identify the element that fits the given characteristics. Brittle solid and a poor conductor of heat and electricity are properties of nonmetals. Among the options provided, element D with an atomic number of 17 (Cl) is a nonmetal at STP.
