An ion is a positively or negatively charged atom or groups of atoms. There are two types of ions: An atom loses one or more electrons from its valence shell. It becomes positively charged. These positively charged atoms are called cations. For example, Sodium (Na) atomic number is 11. So, there is... read more

An ion is a positively or negatively charged atom or groups of atoms. There are two types of ions:

 

  • An atom loses one or more electrons from its valence shell. It becomes positively charged. These positively charged atoms are called cations. For example, Sodium (Na) atomic number is 11. So, there is one electron in the valence shell. To stabilize the atom, sodium loses one electron and is a deficit of the negative charge. This will give rise to sodium ion. Na+

 

  • When an atom gains one or more electrons into its valence shell, it becomes negatively charged. These negatively charged atoms are called anions. For example, the atomic number of Chlorine (Cl) is 17. So, it has seven valence electron and requires one electron to become stable. Thus, chlorine gains one electron and becomes negatively charge. This is called a chloride ion (Cl-)

 

  •  Since there is a loss of electrons in a cation, there is a possibility f losing a shall. Hence the size of a cation is smalled.

 

  •  Since there is a gain of electrons for an anion, there is more number of electrons, causing the shells to repel. This si the reason why an anion is always bigger than its original atom size.

An ion is an atom or a group of atoms in which the number of electrons is different from the number of protons. If the number of electrons is less than the number of protons the practical is a positive ion, also called a cation. Ex : sodium ion Na+ , chloride ion cl- , and oxide ion O2 -.

An atom or molecule when loss or gain electron becomes positively (when loss electrons) or negatively charged(when gain electrons). That atom or molecule is called ion. Types: 1. Anion (ex; I- form when iodine gain one electron) 2 . Cation(ex; Al3+++ form when aluminium losses 3 electrons...

Definition: An isolated atom or molecule with a net electric charge due to the loss or gain of one or more electrons. TYPE: 2 TYPES 1. Cation: Formed by the loss of the electron.Example- Na+ Mg++ 2. Anion: Formed by the gain of the electron. Example- Cl-, O- -

Ion is created either by losing or gaining of electrons by the parent atom.There are two types of ions. Cations(carries positive charge because it lost the electron.Ex: Br+, CH3+ etc..)and Anions(carries negative charge because they gained the electron. Ex: F-, Cl-, OH- etc..)

ion is formed by atoms or molecules loses energy (or) gain energy by loosing electrons then it will forms, then we simply say it is an ion there are two types of ions 1. cation and another one is 2. anion, Example- Na+ Mg++ 2. Anion: Formed by the gain of the electron. Example- Cl-, O- - read more
