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.
Bonds are formed on sharing electrons. Covalent bonds are 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.
covalent bond
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.

Bonds are formed on sharing electrons. Covalent bonds are formed.
A covalent bond is formed when electrons are transferred from atom to atom.
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.
the atoms share electrons
Covalent bonds and dative (coordinate) bonds are formed are formed by sharing electrons between the bonding atoms.
a noble gas
Ionic bonds are formed between metal atoms and non-metal atoms. The metal atoms lose electrons and form positive ions, but the non-metal atoms gain electrons and form negative ions. Since the atoms both now have opposite charges, they are attracted to each other and form an ionic bond.However, covelant bonds are formed between two or more non-metal atoms. The atoms share electrons rather than losing or gaining electrons from each other.
