How are cathode rays originated?
its negatively charged particles of matter,Thomson knew that opposites attract but these the positive charged anode,so he reasoned that the paticles must be negatively charged! : )! Wooooo! Go J.J Thomson
When cathode rays strike a metal target say tungsten what happens?
x-rays are emitted
What is the importance of DC current flow instead of AC during electroplating process?
Electroplating involves moving metal from one electrode to another, through a conductive solution. Typically a metal at the anode will lose an electron, become dissolved in solution, and then move in the solution towards the cathode. Once reaching the cathode, the metal ion gains electron(s) and is thus deposited at the cathode. With AC, the metal ions would just move back and forth in the solution, generating heat but no electroplating.
What is the filament used in tubelight-?
The type of filament used in tube light is that one which is thin and surrounded by an oblong metal shield.
Electroplating is the process of depositing a thin layer of metal onto another by means of?
A solution of ions of the metal to be plated in an ionizing solvent. Electroplating occurs on the cathode imposed by an external electromotive force.
Do metals form at the anode or cathode?
Metals typically form at the cathode during electrolysis. This is because positively charged metal ions are attracted to the negatively charged cathode where they gain electrons and deposit as solid metal.
In electrolysis 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.
What is anode in electroplanting?
In electroplating, the anode is the positively charged electrode that supplies metal ions to be deposited onto the cathode (the negatively charged electrode). As the electric current flows through the electrolyte solution, metal ions from the anode are attracted to the cathode where they are reduced and form a thin layer of metal coating.
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.
How are cathode rays originated?

Why cathode rays are negatively charged?
Cathode rays are negatively charged because they are composed of electrons, which have a negative charge. When a high voltage is applied to the cathode in a vacuum tube, electrons are emitted from the cathode and accelerated towards the anode, creating a beam of negatively charged particles known as cathode rays.
How can we get Sodium metal from electrolysis?
Sodium metal can be obtained from electrolysis of molten sodium chloride (NaCl) using a Downs cell. In this process, the positively charged sodium ion migrates to the negatively charged cathode, where it gains electrons to form sodium metal. The sodium metal then rises to the surface of the molten salt and is collected.
Why During Electroplating The Article To Be Plated Is Always Made The Cathode?
Yes. Electrons will be transferred from the negative cathode to the dissolved metal ions (eg. Ag+ ) in order to let them 'plate' as metal element (eg. Ags ) set to the surface of conductive anode.
What are two positive charged objects?
The nucleus of an atom, which contains protons (positively charged particles), and a positively charged metal rod after rubbing it with a cloth.
What is the attraction between positively charged metal ions and the electons in a metal?
metallic bond
Why do the aluminum ions collect at negative electrodes?
Aluminium is formed at the cathode because the Al ions (Al3+) within the electrolyte are attracted to form aluminium metal by gaining 3 electrons. The metal is molten due to the high temperature of the cells. Hope this helps
What is the force of attraction between positively charged metal ion and the electron in a metal?
electrostatic force
