Why is table salt a poor conducter of electricity?
Usually, solid ionic compounds are weak conductors of electricity. Aqueous solutions of ionic compounds are good conductors though as they have free ions for conductivity. When table salt is dissolved, the solution conducts electricity well.
What are the four properties of non metals?
1. They rarely have metallic luster. 2. They are usually gases at room temperature. 3. Nonmetallic solids are neither malleable nor ductile. 4. They are poor conductors of heat and electricity by Spencer Ferguson
How do solid nonmetals differ from solid metals?
Solid nonmetals typically have lower melting points and boiling points compared to solid metals. Nonmetals tend to be brittle in their solid state, while metals are malleable and ductile. Additionally, nonmetals are usually poor conductors of heat and electricity, whereas metals are good conductors.
What are three general properties of Inonic compounds?
Ionic compounds are formed through the transfer of electrons between a metal and a non-metal. They usually have high melting and boiling points due to strong ionic bonds. Ionic compounds tend to be solid at room temperature and are good conductors of electricity when dissolved in water or melted.
Is cobalt good conductor of electricity?
Ionic bonds usually form between metal and nonmetal atoms, and involve the transfer of an electron from one atom to the other.

Which substance are usually good conductors of heat and electricity?
Metals are usually good conductors of heat and electricity.
What are the minerals gold and copper examples of?
Gold and copper are examples of metallic minerals. Metallic minerals are composed of metals in their elemental form or in a combined state. They are usually shiny, malleable, and good conductors of electricity.
What kind of solid has a high melting point and conducts electricity?
The types of crystalline solids that are usually good conductors of heat and electricity are those that have valence electrons. It is the valence electrons that are responsible for the conduction of heat and electricity.
Metal compounds made of two or more metallic elements are known as?
Metal compounds made of two or more metallic elements are usually called ALLOYS. However, there are true compounds and these are often known simply as inter-metallic compounds.
What are the four properties of non metals?
1. They rarely have metallic luster. 2. They are usually gases at room temperature. 3. Nonmetallic solids are neither malleable nor ductile. 4. They are poor conductors of heat and electricity by Spencer Ferguson
What matrieal that conduct electricity?
Usually Metallic substances conduct electricity and heat- They are good conductors of heat because solid particles are close to each other and vibrate frequently. The properties of metals are shiny usually hard and perpetual- some have special attributes such as aluminum which is light and fairly strong.
Are keys insulators or conductors?
Keys are usually made from some metal or alloy. If they are, they are good conductors, both of heat and of electricity.
Are metal conductor?
Metals are usually good conductors of both electricity and heat.
How do solid nonmetals differ from solid metals?
Solid nonmetals typically have lower melting points and boiling points compared to solid metals. Nonmetals tend to be brittle in their solid state, while metals are malleable and ductile. Additionally, nonmetals are usually poor conductors of heat and electricity, whereas metals are good conductors.
What are some characteristic of most covalent compounds?
Most covalent compounds have low melting and boiling points, are usually gases or liquids at room temperature, and tend to be poor conductors of electricity. They also have localized bonds between nonmetal atoms, where electrons are shared.
Why can ionic compounds conduct electricity but molecular compounds usually can not?
Ionic compounds can conduct electricity because the ions in the solid state can move and carry electric charge. In contrast, molecular compounds usually do not conduct electricity because they do not dissociate into ions in solution or in the solid state, resulting in no free charge carriers to conduct electricity.
