Answer. Explanation: When a salt is melted or dissolved in water, the charged ions conduct electricity. But in solid lithium chloride there are no mobile ions which can carry the charge, since all the particles are locked in a rigid structure.

Electrical conductivity requires the movement of charged particles. A solid ionic compound does not conduct electricity because the ions are not free to move.

Electricity is a flow of electrons. Because lithium (like most other metals) easily gives up its “extra” electron, it is a good conductor of electricity. This tendency to give up electrons also explains other properties of metals such as lithium.

Chlorine is a non-metal substance and hence it is a bad conductor of heat and electricity. Therefore, it cannot work as a conductor.

What Metal is the Best Conductor of Electricity?

• Silver. The best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity.
• Copper. One of the most commonly used metals to conduct electricity is copper.
• Aluminum.

Oxygen is a colorless, odorless, tasteless gas; it is the first member of Group 16 of the periodic table. It is denser than air and only slightly soluble in water. A poor conductor of heat and electricity, oxygen supports combustion but does not burn.

As we know diamond is a giant covalent structure i.e. each carbon atom is covalently bonded with other carbon atoms. So the four outermost electrons, four carbon atoms, are engaged or trapped in the covalent bonds which means that there are no free electrons. So diamond is a bad conductor of electricity.

graphite

Bismuth and tungsten are two metals which are poor conductors of electricity. There are many, but some include Aluminum, Bismuth, Gallium, Indium, Lead, Thallium, Tin, Ununhexium, Ununpentium, Ununquadium, and Ununtrium.

It’s usually mixed with metals, like lead, tin, iron. Bismuth is the diamagnetic of all metals and therefore the thermal conductivity is lower than any metal except mercury.

Graphite

Ductility is a property by which a substance can be drawn into thin wire. few other properties of metals are they are malleable (can be beaten into thin sheets), ductile (can be drawn into wires), and sonorous. Therefore, it is true that all metals are ductile.

While all metals can conduct electricity, certain metals are more commonly used due to being highly conductive. The most common example is Copper. Another common misconception is the pure Gold is the best conductor of electricity. …

steel. …is the hardest and most brittle form of steel. Tempering martensitic steel—i.e., raising its temperature to a point such as 400° C and holding it for a time—decreases the hardness and brittleness and produces a strong and tough steel.

Selenium

Silicon is the non metal which is not brittle.

10 non-metals are solids: Important solid non-metals are: Boron (B), Carbon (C), Silicon (Si), Phosphorus (P), Arsenic (As), Sulphur (S), Iodine (I). 11 non-metals are gases: These are: Hydrogen (H), Nitrogen (N), Oxygen (O), Fluorine (F), Neon (Ne), Chlorine (Cl), Argon (Ar), Krypton (Kr), Xenon (Xe), Radon (Rn).

Non-metals are bad conductors of heat and electricity. Except for graphite which is a good conduction of electricity. Metals are lustrous and can be polished. Metals are solids at room temperature….02 Acid, Bases and Salt.

So, if we include the nonmetals group, halogens, and noble gases, all of the elements that are nonmetals are:

• Hydrogen (sometimes)
• Carbon.
• Nitrogen.
• Oxygen.
• Phosphorus.
• Sulfur.
• Selenium.
• Fluorine.
