Tt depends on the metal which is the cathode and which is the anode. However, in most cases, graphite is the cathode and the metal is the anode. the strictly correct answer is that BOTH the metal and the graphite rod are electrodes. You must have two electrodes minimum to create a cell.
Electron flow is from anode (+) to cathode (-)
Anode is positive and cathode is negative. Cathode is the longest led frame. Anode is where the oxidation reaction takes place while cathode is where the reduction reaction takes place or in a galvanic corrosion the anode is the metal that corrodes while the cathode is protected.
There is no anode and/or cathode when you simply have a tin can in air. There has to be two poles (usually 2 metals that differ in reduction potential). Here you have only 1 metal. But, in a voltaic (galvanic) cell, oxidation takes place at the anode, and reduction takes place at the cathode.
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.

This is the anode.
Anode(:
The Cathode is the negative electrode; the anode is the positive electrode
Electron flow is from anode (+) to cathode (-)
Cathode
In Nelson's cell, an aqueous solution of concentrated NaCl is used for the industrial production of NaOH, while in Down's cell fused or molten NaCl is used for obtaining sodium metalIn Nelson's cell, three main chemicals are obtained as products that are Hydrogen gas, Chlorine gas and NaOH whereas in down's cell chlorine gas and sodium metal is produced as a product.In Down's cell, graphite is used as anode and iron is used as cathode. But, in Nelson's cell perforated steels is made cathode and grapite as anode.
Oxidation occurs at the anode ("an ox") and reduction occurs at the cathode ("red cat").See the Web Link to the left for the specific reaction in a dry cell.
An anolyte is the portion of an electrolyte near an anode, especially in a cell in which the cathode and anode are in separate compartments.
The correct answer is Electrons flow away from the anode and also Oxidation occurs at the anode.
