Answer:
HgBr2 conducts when molten because there are mobile ions in molten HgBr which allows flow of current when an electrical potential difference is introduced to the HgBr in molten state
However HgBr2 does not conduct in the solid state as the ions are fixed in the solid HgBr2 lattice structure
Mercury, which is a metal in its natural form conducts both in the solid and molten states as the delocalized electrons are able to move both in the solid and molten mercury states and as such current flows through mercury when there is an electrical potential difference placed across it
Explanation:
Electricity or electric current flow is the term used to describe the state of movement or flow of matter that carries an electrical charge
It is the steady movement of or flow of electrons. The moving electrons transfer electrical charge round an electrical circuit. In metals, there are freely shared electrons between individual atoms so as to efficiently conduct electricity and so when an electrical potential difference is placed across a piece of metallic object an electron is readily displaced by another electron entering from one end and exiting from the other end of the electrical potential difference
The electrical conductivity of mercury bromide and mercury in the solid and molten state has been because of the loosely bonded atoms, resulting in the flow of electrons.
Electrical conductivity can be defined as the flow of electrons. Mercury bromide has been an ionic compound. In the molten state, there has been the ionic form of the compound. It results in the flow of ionic current and thereby the compound has been consisted of the electrical conductivity in the molten state.
In the solid-state of mercury bromide has a compact lattice and there has been no flow of electric current.
The mercury has been the liquid metal, and the atoms are loosely bound. On the application of the small amount of voltage, there has been a flow of atoms resulting in electrical conductivity.
