Question

What is a negative electrode called?

Answer 1

In order to answer this question, to know the exact term for a negative electrode or the term which is called negative electrode, we will go through the term and then we will discuss why the required term is called a negative electrode.

Complete answer:
The negative electrode in electrolysis is called the cathode. The positively charged ions move towards the cathode.
A cathode is the electrode from which a polarised electronic device's conventional current leaves. The mnemonic CCD for Cathode Current Departs can be used to remember this definition. The direction in which positive charges move is described by a conventional current. Because electrons have a negative electrical charge, their movement is the polar opposite of traditional current flow. As a result, the mnemonic cathode current exits also signifies that electrons from the external circuit flow into the device's cathode.
The polarity of the cathode in relation to the anode might be positive or negative depending on how the device is used. Although cathode polarity varies depending on the device type and can even vary depending on the operating mode, positively charged cations always go towards the cathode and negatively charged anions always move towards the anode.
The cathode is negative (electrons flow into the cathode, and charge flows out of it) in a device that absorbs charge energy (such as recharging a battery), and positive (electrons flow into the cathode, and charge flows out of it) in a device that delivers energy (such as a battery in use): The positive terminal of a battery or galvanic cell is the cathode, which is where the current flows out of the device. Positive ions travelling from the electrolyte to the positive cathode carry this outward current internally.

Note:
When we talk about the cathode in chemistry, we're talking about the electrode where the reduction happens. This is a regular occurrence in an electrochemical cell. The cathode becomes negative as a result of the electrical energy given to the cell causing chemical compounds to decompose.
