Atoms form ions so that they can have a full valence shell of electrons (sometimes called an octet). Many atoms will lose electrons and become positive ions, so that their electron configuration is like that of a noble gas. Certain atoms can gain electrons, becoming negative ions to reach a noble gas configuration.
Ionic bonds are formed when calcium atoms react with oxygen atoms. Calcium tends to lose two electrons to form a positive ion, while oxygen tends to gain two electrons to form a negative ion. The strong electrostatic attraction between the positive calcium ion and the negative oxygen ion results in the formation of an ionic bond.
Barium is unlikely to form a positively charged ion because it is an alkaline earth metal with a strong tendency to lose electrons and form a 2+ ion.
Sodium ion (Na+) is a positively charged ion that forms when sodium atoms lose their outermost electron. Chloride ion (Cl-) is a negatively charged ion that forms when chlorine atoms gain an electron. The symbol for sodium ion is Na+ and for chloride ion is Cl-.
Charged particles that form when atoms gain or lose electrons are called ions. When an atom gains electrons, it becomes a negatively charged ion (anion). When an atom loses electrons, it becomes a positively charged ion (cation).
The oxygen atoms in the nitrate ion have a hybridization of sp.
None the formation of an ion has nothing to do with losing or winning atoms.
an atom which readily losses or gains electrons to attain stability forms an ion.
