Not exactly. The atoms of elements can gain or lose electrons and become ions. Ions are charged particles that have gained or lost electrons. The atoms of elements can gain or lose electrons to form monatomic ions (made from a single atom of an element).
Atoms of elements that gain electrons develop a negative charge, such as the sulfide ion,
The atoms of elements which lose electrons develop a positive charge, such as the aluminum ion,
There are also polyatomic ions, nearly all of which are negatively charged. They are formed when two or more atoms of different elements covalently bond, but end up with one or more extra electrons. One example, the sulfate ion,
In some circumstances it is possible for elements to contain ions.
In metallic bonding we assume that the outer electrons are not localised to a particular atom but are free to move throughout the crystal

So we have metal ions surrounded by a "sea" of negative electrons.
This model accounts for some of the physical properties of metals. They are malleable, ductile and are good conductors of electricity.
However the electrons are not lost as in ionic bonding so we cannot write a symbol such as
At high voltages it is possible to ionise gases. A high energy electron can "knock off" an electron from a neutral molecule:
This happens in electrical discharges.
At very high temperature plasma contains gaseous ions in equilibria with electrons. This is sometimes referred to as the "fourth state of matter".
