GENERAL KNOWLEDGE

Detailed explanation-1: -Therefore, an atom that loses electrons becomes a positively-charged ion called a cation.

Detailed explanation-2: -Ions are atoms that have a positive or negative charge because they have unequal numbers of protons and electrons. If atoms lose electrons, they become positive ions, or cations. If atoms gain electrons, they become negative ions, or anions. Consider the example of fluorine (see Figure below).

Detailed explanation-3: -When an atom loses or gains an electron, ions are formed. If an atom loses electron it forms positive charge and if gains electron it forms negative charge. An atom which carries charge on it is known as ion.

Detailed explanation-4: -Neutral atoms can be turned into positively charged ions by removing one or more electrons. A neutral sodium atom, for example, contains 11 protons and 11 electrons. By removing an electron from this atom we get a positively charged Na+ ion that has a net charge of +1.
