Electrons are subatomic particles with a negative charge that orbit around the nucleus of an atom in specific energy levels. They play a crucial role in chemical reactions by participating in bonding between atoms. Electrons also exhibit wave-particle duality, meaning they can behave as both particles and waves.

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.
Is it true that current is a the rate of flow of electrons?
Yes, current is the flow of electric charge, typically carried by electrons in a conductor. It is measured in amperes and represents the rate at which electrons pass through a given point in a circuit.
Which of the following is NOT a basic element of knowledge?
Opinion is NOT a basic element of knowledge. Knowledge is based on facts, evidence, and information that is true and verifiable. Opinions are subjective beliefs or judgments that may not be based on actual evidence.
Valence electrons are the electrons found on the last shell of an atom true or fase?
True
Is it true in the phenomenon known as the photoelectric effect electric current will flow when light shines on certain substances?
Yes, in the photoelectric effect, when light shines on certain substances, electrons are ejected from the material, creating an electric current. This effect occurs when photons (light particles) transfer enough energy to electrons in the material to overcome the binding energy holding them in place.
What is a true of our current knowledge of electrons?
electrons from a cloud around the nucleus
What is true of our current knowledge of electrons?
electrons from a cloud around the nucleus
True or False. The imbalance of electrons in an atom creates a movement of electrons called the electric current?
False. The imbalance of electrons in an atom does not create electric current. Electric current is the flow of electric charge, which is the movement of electrons through a conductor. The movement of electrons in an atom due to an imbalance is known as an electric field, which can lead to the flow of electric current when a conductor is present to allow the movement of electrons.
Is it true a current is the movement of negative charges called electrons?
Yes, a current is the flow of electric charge, typically carried by negatively charged electrons moving through a conductor. The motion of these electrons constitutes an electric current.
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.
Is it true scientific models are based on current knowledge which can limit their effectiveness when new discoveries are made?
TRUE
When electric current is following in a curcuit if the voltage applied to the curcuit is increased the resistance will decrease true or false?
true
Is current the moving of negative electons?
Yes, current is the flow of electric charge, which is typically carried by negatively charged electrons moving through a conductor in a circuit. When electrons move, they create an electric current.
Which of the following is true regarding current scientific thought?
RNA originated before DNA
Is it true that current is a the rate of flow of electrons?
Yes, current is the flow of electric charge, typically carried by electrons in a conductor. It is measured in amperes and represents the rate at which electrons pass through a given point in a circuit.
Is it true that a battery produces alternating current?
No. A battery produces DC, or Direct Current.
Which of the following IS NOT true regarding the core values knowledge and skills of CPS practice?
first tell us what 'the following' are.
