During the sputtering process in a hollow cathode lamp, a gas, typically an inert gas like argon, is ionized within the hollow cathode by applying a high voltage. This ionization creates positively charged ions that collide with the cathode material, causing atoms to be ejected or "sputtered" from its surface. These ejected atoms then enter the gas phase and can be excited by the energy from the plasma, leading to the emission of light at characteristic wavelengths when they return to a lower energy state. This process is crucial for generating the specific spectral lines used in various analytical applications, such as atomic absorption spectroscopy.

What happens to the lead ions at cathode?
At the cathode during an electrochemical process, lead ions (Pb²⁺) are reduced to solid lead (Pb) through the gain of electrons. This occurs as the lead ions migrate towards the negatively charged cathode and undergo a reduction reaction, resulting in the deposition of lead on the cathode surface. This process is commonly observed in lead-acid batteries during discharge.
What forms at the cathode during electrolysis of a metal compound?
At the cathode, the metal ions in the compound gain electrons and are reduced to form solid metal atoms. This solid metal deposits on the cathode during the electrolysis process.
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.
What is Annode and Cathode in Chemistry?
In chemistry, the anode is the electrode where oxidation occurs during an electrochemical reaction, while the cathode is the electrode where reduction occurs. Electrons flow from the anode to the cathode. This process is essential in batteries, electrolysis, and other electrochemical systems.
Which metal acts as the cathode during silver plating?
Cathode, as the fork attracts silver cations (+ ions)

What is the process of electrorefining?
In an electro-refining system the deposited metal is collected without the need to remove the cathode from the slurry bath. The cathode has a hollow cavity permitting steam or hot water to be introduced to heat the cathode. During the deposition process, the heating of the cathode encourages the deposition process. When the deposited material is to be collected, the cathode is heated to "melt" the bonds between the cathode and the deposited metal. Using a bracket which was installed before the deposition process and into which the deposited metal has been formed; the now-released sheet of deposited metal is easily removed.
What would the cathode be in a nickel and copper electrolytic?
Ni(s)

Why cathode steel used for production of brine?
Cathode steel is used for the production of brine because it is resistant to the corrosive effects of the brine solution. This helps to ensure the longevity and efficiency of the equipment used in the brine production process. Additionally, cathode steel is a suitable material for maintaining the purity of the brine solution during production.
