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.
An ionic bond is most likely to form between two elements that have a?
large difference in electronegativity, where one element has a strong tendency to attract and gain electrons while the other has a strong tendency to lose electrons. This creates a transfer of electrons from one element to another, resulting in the formation of charged ions that are then attracted to each other by electrostatic forces to form an ionic bond.
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
This is when atoms of elements combine by sharing electrons or by the complete transfer of electrons from one atom to another?
This process is known as chemical bonding. Atoms can form covalent bonds by sharing electrons, or ionic bonds by transferring electrons. The type of bond formed depends on the electronegativity difference between the atoms involved.
What is the main difference between these two ions?
One has gained electrons and the other has lost electrons
What is the major difference between ionic and covalent bonds?
The major difference between ionic and covalent bonds is how electrons are shared between atoms. In an ionic bond, electrons are transferred from one atom to another, creating ions that are attracted to each other. In a covalent bond, electrons are shared between atoms, resulting in a sharing of electron density between the 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
In charging by rubbing electrons move from one material to another because blank?
In charging by rubbing, electrons move from one material to another because of the difference in affinity for electrons between the two materials. When two materials are rubbed together, one material gains electrons (becomes negatively charged) while the other loses electrons (becomes positively charged), resulting in the transfer of electrons between the materials.
What is the difference between a covalent bond that is polar and one that is not?
In a polar covalent bond, electrons are shared unequally between atoms, resulting in a partial positive and partial negative charge on the atoms involved. In a nonpolar covalent bond, electrons are shared equally between atoms, resulting in no significant charge difference.
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.

This is called a potential difference (or voltage difference).
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".
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.
How does the difference in electronegativity between two atoms affect the nature of their bond, specifically in terms of making it ionic?
The difference in electronegativity between two atoms affects the nature of their bond by determining if it is ionic. When there is a large difference in electronegativity, one atom will attract the shared electrons more strongly, leading to the formation of an ionic bond where one atom gains electrons to become negatively charged (anion) and the other loses electrons to become positively charged (cation).
What is the difference between one and one's?
difference between one- ones
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.
