The element forming at the cathode will depend on what elements are present. Reduction takes place at the cathode, so whatever element is being reduced, that is the one that will be produced at the cathode.

What is the cathode in an electrochemical cell?
The electrode at which a reduction reaction occurs.PhysicsA cathode is the element of an electron tube from which electrons flow. Back in the day, current was thought to be positive, but we understand things differently now. In the "old school" version, the cathode was the element into which positive charges flowed. But that's usually not what is taught for the simple reason that it's a classical physics approach and isn't at all as useful as the idea that the cathode is the element from which electrons leave to go to the plate.In a two-element tube, the cathode has a compliment called the anode, or plate. Electrons flow from the cathode to the anode. Not the other way. There are tubes with three, four, and more elements, but they have these two basic elements.ChemistryThe cathode is the electrode of a polarized electrical device, such as a galvanic cell, out of which positive electric current flows. In a battery like the one in a vehicle, the positive terminal is the cathode. The car battery, which is a lead-acid battery, also has an electrode that is the compliment to the cathode: the anode. It's the negative terminal of the battery, and positive electric current flows into this electrode.The Wikipedia article on the cathode covers both the chemistry application of the term as well as the physics application, and a link is provided.
Which element is the reference element is chemistry?
Carbon is the reference element for the definition of the mole. In electrochemistry, the reference element/electrode is the Hydrogen electrode and all electrode potentials are against the hydrogen standard.
What element makes up the center electrode post of ordinary flashlight batteries?
carbon
How is astatine produced what element is it most similar to?
Astatine is produced by nuclear reactions.
Are electrons positive or negative in aluminium?
Electrons are always negative, regardless of the element they are in.
What type of electrode is a cold cathode?
Cold cathode is a cathode, an electrode that emits electrons, which is not electrically heated by an element. Cold cathodes are used in gas discharge lamps such as neon lamps and discharge tubes.
What element is in center electron post of a battery?
We find carbon or graphite as the center electrode of a zinc-carbon battery. It's the "common" battery we use in lots of stuff (but not an alkaline battery). That center electrode is the positive one, and the zinc makes up the outer or negative electrode in this battery. In an alkaline battery, manganese dioxide is the center, or the cathode (positive electrode). Powdered zinc will be found as the outer or negative electrode (anode).
What element is negative electrode in the common flashlight battery?
Zinc

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 invention in the 1940 was first used in a car using 2 pieces of metal and is rechageable and is now smaller?
the invention was a tri-ode diode which is an electronic gas filled tube with an anode and a cathode and one more switching element. The anode is actually the negative plate and the cathode is the positive side. The third element is a switch for on and off.
What element is the center of electrode post of ordinary flashlight batteries?
brass
What compound and element is produced after photosynthesis?
Oxygen is the element produced after photosynthesis.
What element makes up the center electrode post of ordinary flashlight batteries?
carbon
Describe how an hollow cathode lamp work?
The typical hollow cathode lamp consists mainly of a cathode containing the element of interest, an anode, and an inert gas. After application of a potential difference between the cathode and the anode, the gas will accelerate toward the cathode removing its material; a process called sputtering. The element of interest is now in the excited state, and upon its return to the initial non-excited state, it would emit light waves of specific wavelength, that can be studied later.
Why are sodium ions attracted to the negative electrode?
Sodium's electron configuration means that there is just one electron in its outer shell, when becoming an Ion it is easier for it to "donate" this electron to the element it is forming a compound with. This means that the Sodium ion is no longer electrically balanced (it has lost a negatively charged electron) and becomes overall positively charged. Being positively charged it will of cause be attracted to the NEGATIVE electrode as oposite charges attract and similar charges repel.
