Positive ions.
metallic bond
Most atoms have the ability to lose electrons, given the conditions are favorable, e.g. in a chemical reaction, but the ones that loose their electrons easiest are the ones with only a few electrons in their outer shell, such as the alkali metals and alkaline earth metals which only have 1 and two electrons, respectively.
of course, ions are formed by loosing (cations) or gaining (anions) electrons. anions have more electrons than the atom from which it is formed.
In forming compounds, atoms are engaged in either gaining or losing electrons. They may also share electrons, but that is also a form of gaining or losing electrons.
Bonds are formed on sharing electrons. Covalent bonds are formed.
metallic bond
cations are positively charged ions formed by loss of electrons from the neutral atoms having 1,2,3 valence electrons
This chemical bonding is called ionic bonding.
When atoms or molecules gain or lose electrons, they are best described as becoming ions. Ions are charged particles that are formed through the process of gaining or losing electrons.
Ions are not formed in a covalent bond because in a covalent bond, atoms share electrons instead of transferring them. This sharing of electrons allows both atoms to achieve a stable electron configuration without gaining or losing electrons to become charged ions.
The two types of ions are cations and anions. Cations are formed when atoms lose electrons, resulting in a positively charged ion, while anions are formed when atoms gain electrons, resulting in a negatively charged ion.
Cations are formed by atoms losing electrons, resulting in a positively charged ion. This occurs when atoms from metals and certain nonmetals give up electrons to achieve a stable electron configuration. The loss of electrons creates a deficiency of negative charge, leading to a positive charge on the cation.

An ion is formed by losing one or more electrons. When an atom loses electrons, it becomes positively charged and is called a cation.
