* The atom that loses the electron becomes a positively charged ion (cation). This is because it now has more protons (positively charged particles) than electrons (negatively charged particles).
* The atom that gains the electron becomes a negatively charged ion (anion). This is because it now has more electrons than protons.
* An ionic bond is formed between the two ions. This is a strong electrostatic attraction between the oppositely charged ions.
This process is called electron transfer and is a fundamental concept in chemistry. It is responsible for the formation of many ionic compounds, which are essential for a wide range of chemical reactions and biological processes.
