Where do the electrons in a covalent bond come from?

The electrons in a covalent bond come from the outer energy levels of the atoms involved. Each atom contributes one or more electrons to be shared between them. This sharing creates a stable electron configuration for both atoms.


From which terminal of a battery are electrons pushed?

electrons come from the negative terminal, then goes around the complete circuit (clockwise) and comes back to the positive terminal. hope that helps!

Is the flow of electrons currently in the circuit?

Yes, the flow of electrons is currently present in the circuit.


What supplies the electrons that will flow through the circuit?

The metals making up the circuit contain electrons themselves, and when they are together they form a conduction band (a 'sea' of delocalised electrons moving freely around positive atomic kernels) between the bonded metals. So no electrons are actually 'poured in', they are just pushed around.


Electrons move in a circuit and have millions and millions of what?

Electrons move in a circuit and have millions and millions of collision's.


What is the relationship between the voltage applied to a circuit and the velocity of electrons within that circuit?

The relationship between the voltage applied to a circuit and the velocity of electrons within that circuit is direct. When a higher voltage is applied to a circuit, the electrons within the circuit move faster, resulting in an increase in their velocity.


A closed path through which electrons can flow is?

An electrical circuit is a closed loop through which electrons can flow. It typically consists of a power source (such as a battery), conductive wires, and components like resistors and lightbulbs that use the flow of electrons to perform various functions.


What type of circuit allow electrons to flow constantly?

an open circuit allows electrons to flow constantly


How do circuit breakers keep the wire in an electrical circuit from overheating?

They reduce the flow of electrons.


Is true if there is voltage in circuit there must be electrons flowing through the circuit.?

No. For electrons to flow, you need a current.


In which direction do electrons flow from the anode to the cathode in an electrical circuit?

Electrons flow from the anode to the cathode in an electrical circuit.
