Sodium (Na): Sodium is a metallic element that reacts vigorously with water and air. When combined with chlorine, it forms table salt.
Chloride Ion (Cl): A chloride ion is formed when a chlorine atom gains one electron during chemical reactions like combining with sodium to create table salt.
Ionic Bonding:Ionic bonding is a type of chemical bond formed between two oppositely charged ions, such as sodium and chloride ions in the case of table salt.
