Very briefly, no.
First, ions do not combine to form molecules. Ions are formed by transferring electrons; molecules are formed by sharing electrons. Ionic substances are held together by attraction of positive and negative ions, much like magnets.
In both ionic and molecular substances, once bonds are made, electrons cannot move from atom to atom, ion to ion, or molecule to molecule. Because the electrons cannot move, no current can flow.
As a side note, ionic substances can conduct if the ionsbecome mobile by melting the substance or dissolving it in water.
What else can I help you with?
Is medium necessary for flow of current?
Current requires a medium to flow through, gas, liquid or solids. In metals, free electrons allow passing of current from one region to another. In non-metals, they would have to be molten for the molecules to pass the current around since the molecules in a solid can only vibrate. In gases, the molecules are free to move about, allowing current to be conducted (I suppose).
Can a current flow in a wire with a free end?
No, a current cannot flow in a wire with a free end because there is no complete circuit for the current to flow through. In order for current to flow, there must be a closed loop circuit for the electricity to circulate through.
Is a electric current a flow of electricity?
The flow of electrons from a body at a higher voltage to one at a lower voltage is flow of current.
What is the direction of current due to flow of electrons if it is not conventional current?
The direction of current due to flow of electrons is opposite to the direction of conventional current. This is because electrons have a negative charge, so when they flow in a wire, they are actually moving in the opposite direction to the current flow defined by convention.
Why do rivers flow very fast?
because the current
Why must a circuit be closed in order for a current to flow?
A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.
What causes a current in an electrical current?
Electrons flow because of electrical attraction and repulsion.
Why fault current can be extremely high?
Because the impedance to current flow is very low.
Why DC supply is need in thyrister?
because thyrister doesn't allow the current to flow unless there is a current flow into the gate. this current must be dc, and the rating of this current depends on the type of thyrister.
Corrosion in a circuit results in high current flow?
When there is corrosion in a circuit, it results in lower current flow. This is because corrosion actually causes resistance.
Why must a circuit be closed in order for current to a flow?
A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.
How is current flow in an AC-DC converter?
because of potential difference.
