I'm an expert in the field of chemistry, and I'm here to provide you with a detailed explanation of how a negative ion is formed.
Negative ions, also known as anions, are formed through a process known as ionization. This process involves the transfer of electrons from one atom or molecule to another. When an atom or molecule gains one or more electrons, it becomes negatively charged because electrons carry a negative charge. The formation of a negative ion can be described through several steps:
1. Electron Affinity: The first step in the formation of a negative ion is the affinity of an atom or molecule for additional electrons. Different elements have varying tendencies to gain electrons. This is due to the atomic structure and the distribution of electrons in their orbitals.
2. Electron Transfer: The atom or molecule that has a high electron affinity will attract and accept an electron from another atom or molecule. This transfer can occur through various means, such as chemical reactions, physical processes, or even exposure to certain types of radiation.
3. Formation of Negative Charge: Once the electron is transferred, the atom or molecule that received the electron now has more electrons than protons. This imbalance results in a net negative charge.
4. Stabilization: After the formation of the negative ion, the atom or molecule may undergo various processes to stabilize its new charge. This can include the rearrangement of electrons in its orbitals or the formation of bonds with other atoms or molecules.
5. Attraction to Positive Charge: As a result of its negative charge, the newly formed anion will be attracted to positively charged particles, such as cations or the anode in the context of electrolysis.
It's important to note that not all atoms or molecules can easily form negative ions. The ability to do so is influenced by factors such as electronegativity, ionization energy, and the overall stability of the resulting ion.
In the context of electrolysis, the process is facilitated by an electric current that drives the movement of ions. The anode, which is the positive electrode, attracts the negatively charged ions (anions) towards it. Conversely, the cathode, which is the negative electrode, attracts positively charged ions (cations).
The formation of negative ions is a fundamental concept in chemistry and is crucial for understanding various phenomena, including the behavior of ions in solutions, the conduction of electricity in ionic compounds, and the principles of electrochemistry.
Now, let's move on to the translation of the above explanation into Chinese.

an electrically charged atom or group of atoms formed by the loss or gain of one or more electrons, as a cation (positive ion) which is created by electron loss and is attracted to the cathode in electrolysis, or as an anion (negative ion) which is created by an electron gain and is attracted to the anode.
