Why is bromine a bad conductor of electricity?
Bromine is composed of uncharged molecules whose electrons, unlike those of metals, are tightly bound to the atoms and do not form a conduction band. Thus, there are no mobile charge carriers that will move in response to an electric potential.
Can bromine conduct electricity as a liquid?
Yes, bromine is the only liquid non-metal known at room temperature. … due to which ions of Br are produced which can conduct electricity along with Na ions. But still Br is a non-metal thus its conduct electricity to very small extent.
Why does liquid iodine not conduct electricity in terms of particles?
Iodine does not conduct electricity since each molecule of iodine comprises twoiodine atoms joined by a covalent bond that cannot be excited sufficiently to transfer electrical energy.
Why do liquids not conduct electricity?
The more ions present, the more current can be carried. Pure water forms very few ions and does not conduct electricity very well. … Some compounds such as sugar, dissolve in water but do not form ions. Some liquids such as oil or alcohol do not form ions and do not conduct electricity.
Is bromine a poor conductor of electricity?
This structure means that bromine is a very poor conductor of electricity, with a conductivity of around 5 × 10−13 Ω−1 cm−1 just below the melting point, although this is higher than the essentially undetectable conductivity of chlorine.
Why nacl is a conductor of electricity in molten state?
In the solid state, ionic compounds such as sodium chloride have their ions fixed in position and therefore these ions cannot move so solid ionic compounds cannot conduct electricity. However in the molten state, ions in ionic compounds are free to flow and therefore molten sodium chloride can conduct electricity.
Can phosphorus conduct electricity?
No, phosphorus cannot conduct electricity.
Can kerosene conduct electricity?
Petrol and kerosene oil have very low electrical conductivity and hence they are poor electrical conductors (i.e. insulators).
Is liquid bromine flammable?
Bromine is not combustible but it is a STRONG OXIDIZER which will enhance the burning of other materials. Extinguish fire using an agent suitable for type of surrounding fire. POISONOUS GASES ARE PRODUCED IN FIRE Use water spray to keep fire-exposed containers cool.
Why does magnesium oxide conduct electricity as a liquid?
Some of the physical properties of sodium chloride and magnesium oxide are explained because: > there are strong attractions between positive and negative ions, which have to be overcome, so they have high melting points; … > ions can move in solution or in a molten liquid so these conduct electricity.
Why does iodine sublime in terms of molecular covalent structure?
A crystal of iodine sublimes from its solid state to its gaseous state without turning into a liquid. Iodine forms a molecular covalent crystal. This means that there are strong covalent bonds within the molecules of I2 but weak Van der Waals forces holding the molecules of I2in the crystalline structure.
Is iodine a conductor of electricity?
The other options- iodine, sulphur and bromine are non-metals. Hence, they are bad conductors of electricity.
Why are liquids not as good conductors of electric current as metals?
The reason is that the atoms in metals are compactly packed which makes them good conductors of electricity. But in liquids the atoms are relatively loosely packedand have some space in between them which makes them poor conductors of electricity as compared to metals.
How does electricity conduct through liquids?
A conducting liquid or electrolyte contain ions that is positively charged and negatively charged ions. The flow of these ions conduct electricity through the conducting liquid or electrolyte. The solution of acids ,bases and salts in water are electrolytes.
What element is a liquid that does not conduct electricity?
There are some exceptions to the general properties of nonmetals. For example, carbon can conduct electricity, although it has all other nonmetal properties. Bromine is a liquid at normal temperatures, and it is the only liquid non-metal.
