Ionization or ionisation, is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes. The resulting electrically charged atom or molecule is called an ion.Ionization can result from the loss of an electron after collisions with subatomic particles, collisions with other atoms, molecules.

Apr 02, 2019  · Halogen elements are very reactive. They produce salts with sodium, of which table salt (sodium chloride, NaCl) is the most well-known. The halogen elements have seven valence electrons in their outermost electron shell. Therefore, when these elements can receive an electron from another atom, they form very stable compounds since their outermost shell is full.
