Why do charges flow in wires?
Electronic charges will flow when a potential difference between the two locations, and an adequate path between them exists (with a low enough dielectric constant to allow the flow of charge - such as a wire). Electrons will move from here to there because there are "extra" electrons here, and there's some "missing" electrons there. Electrons have a specific charge. If you have "extra" electrons at one location relative to "missing" electrons at another location, you will have a negative voltage here, and a positive voltage (relative to here) there. This is called a potential difference (or voltage difference).
What is the difference between potassium and aluminum?
potassium belongs to group 1 and has one valence electron. aluminium belongs to group 13 and has three valence electrons.
What the difference between covalent and ionic bonds?
An ionic bond is in which one atom steals at least one electron from another atom in attempt to fill it's electron shell. A covalent bond is whose electrons are shared between atoms
How does electrons transfer from one atom to another?
When we apply potential difference to a conductor, by potential force, free electrons gets energy and move low to high potential thus electrons move one atom to other atom.
How can you compare atom and cation?
An atom is a neutral structure consisting of a single nucleus with its orbiting electrons. A cation is a positively charged structure consisting of a single nucleus with its orbiting electrons. The major difference between an atom and a cation is that the cation has lost one or more electrons and therefore has a positive charge overall.
What is the main difference between these two ions?
One has gained electrons and the other has lost electrons
What is the difference between covalent bonds and ionic bonds?
An iconic bond is formed when one or more electrons are transferred from one atom to another. And a covalent bond forms when electrons are shared between atoms
What is difference between electrical and electricity?
Electrical is an one type of energy ie flow of electrons... this flow of electrons constitutes the Electricity which we are using for our use
The difference between ionic compounds and covalent compounds?
An ionic bond is when one or more electrons are transfered from one atom to another. A covalent bond is when atoms share one or more electrons. The atom Hydrogen would need only 2 electrons but most need 8.
Difference between static electricity and dynamic electricity?
There are two types of electricity; dynamic and static electricity. The main difference between these two types is that in static electricity, the electrons do not move but in dynamic electricity, the electrons move either in changing directions or in one direction.
Why do charges flow in wires?

The movement of electrons between two points is called voltage?
No. "Voltage" is the difference of electric potential between two points ... the 'pressure' that electrons would feel to move from one point to another if there's a conducting path. The actual flow of electrons between two points is electric "current".
How is a potential difference achieved?
by creating two regions one region with more number of electrons than the other we can obtain potential difference between the two regions.
What is the difference between a shared pair and unshared pair of electrons?
A shared pair of electrons are two electrons in a covalent bond that alternate between atoms; one electron from one atom and one electron from the other atom. If you were to draw a dot diagram, two dots (standing for electrons) would be between the two atoms, one for each atom. Unshared pairs are two electrons that are not involved in a bond and have already filled their shells. In a dot diagram there would be two electrons paired together on one side of an atom, but not shown to be part of the bond.
Does the electron oscillates in the conductor or the move from one site to another in the conductor?
When a potential difference exists between two points of a conductor, electrons slowly drift between those two points along that conductor. If there is no potential difference within the metal, then the electrons simply float randomly between atoms within the metal. Electrons would only oscillate in response to an external, oscillating voltage.
Describe the difference between ionic and covalent bonds?
In a covalent bond electrons are shared between atoms. In an ionic bond electrons are transferred from one atom to another, resulting in oppositely charged ions.
What is the difference between Chloride and callcium?
Chloride is an ion of chlorine plus one electron. In solution, calcium is an ion missing two electrons.
