In electrolysis electrons move between two metal strips called?
Electrodes, the positive side is called the Cathode and the Negative side is called the Anode.The anode and cathode. The anode is positively charged and the cathode is negative.
Name of one electrode and say is positive or negative?
The Cathode is the negative electrode; the anode is the positive electrode
In a cathode ray tube where do the particles originate and what do they move toward?
The particles originate from the Cathode in the neck of the tube. They are liberated by a heater. The electrons thus liberated are attracted by the Anode, by applying a high voltage to it. In a CRT there are several anodes, the largest and biggest is formed by a coating inside the tube towards the screen. This attracts and accelerates the electrons in a stream of particles known as a 'cathode ray'. They carry on in a straight line, once accelerated, until they hit the screen and cause a phosphor coating to glow, on the inside surface of the screen. The cathode ray can be bent from it's course, by using electromagnets arranged around the neck of the tube.
The em value of cathode rays is always constant but the em value of positive rays is not constant why?
Anode rays differ from cathode rays in several aspects and their specific charge(charge/mass or e/m ratio) is an important feature. The reason lies in how anode rays are produced. Anode rays are produced when a gas at low pressure is subjected to a high voltage(10,000 Volts). Under these conditions, the atoms of the gas get ionized, i.e. they lose some electrons and thus become cations(positive ions). It is a stream of these positive ions that become 'anode rays'. However, the atomic masses of different gases are different and hence, the mass of anode ray particles varies when you use different gases in the discharge tube and hence, the charge/mass ratio also varies. Whereas, in the case of cathode rays, the cathode ray particles are nothing but electrons. Their charge and mass is constant no matter what gas you use in the discharge tube. So, their charge/mass ratio remains constant. (ANSWER BY RIZWAN FROM PAKISTAN)
What did eugen goldstein contribute in the history of atom?
He is sometimes called the discoverer of protons. He did experiments with cathode ray tubes, which knock electrons off atoms and attract them to a positively-charged electrode (the cathode). He noticed that a second stream of particles was attracted to the negatively-charged electrode (the anode), so he called them anode rays. However, it was left to one of his students to discover that these rays were sometimes pure protons. His experiments gave him a picture of atomic structure that was decades ahead of its time, and similar to what we know today. However, he did not follow up on his work, and was largely ignored by his peers.
Why flow of current from cathode to anode still the flow of electrons is from cathode to anode?
The conventional current flow from cathode to anode is a historical convention established before the discovery of electrons. Electrons, being negatively charged, actually flow from the anode to the cathode in an electric circuit. However, because the flow of positive charges is analogous to conventional current flow, it is discussed in terms of current flowing from the cathode to the anode.
What is the ion release in between cathode and anode?
Ions are released at the anode during oxidation, and they move towards the cathode through the electrolyte. At the cathode, the ions gain electrons and are reduced. This process results in the transfer of ions between the cathode and anode.
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.
What is cathode and anode?
cathode is electron negative but anode is positiveAnswerFor electrochemical cells, electrons travel through the external circuit from the anode to the cathode.
In electrolysis electrons move between two metal strips called?
Electrodes, the positive side is called the Cathode and the Negative side is called the Anode.The anode and cathode. The anode is positively charged and the cathode is negative.
In a simple cell the cathode or the anode is more reactive?
In a simple cell, the anode is typically more reactive than the cathode. The anode undergoes oxidation, releasing electrons, while the cathode undergoes reduction, accepting those electrons. This difference in reactivity drives the flow of electrons from the anode to the cathode, generating electrical energy.
What are the uses of Cathode Rays and Anode Rays?
cathode rays can emit electrons anode can collect them
The relationship between a cathode and an anode involves what?
The relationship between a cathode and an anode involves
What is the relationship between the cathode and anode in an electrochemical cell?
In an electrochemical cell, the cathode is where reduction occurs, while the anode is where oxidation occurs. The cathode and anode are connected by an external circuit, allowing for the flow of electrons from the anode to the cathode. This flow of electrons generates an electric current in the cell.
What is the difference between the cathode and anode in an electrical circuit?
In an electrical circuit, the cathode is the negatively charged electrode, while the anode is the positively charged electrode. The cathode attracts electrons, while the anode releases electrons.
What is the difference between anode and cathode in terms of their functions in an electrochemical cell?
In an electrochemical cell, the anode is where oxidation occurs, releasing electrons. The cathode is where reduction occurs, accepting electrons. This creates a flow of electrons from the anode to the cathode, generating electrical energy.
How a battery cause electron in move in a circuit?
It is an oxidation/reduction reaction. Electrons flow from anode to cathode.
