There is an attraction of the nucleus for electrons. This attractive force must be overcome to remove an electron. The energy to overcome this attraction and remove an electron from the atom is 'ionization energy'.
Rubbing an insulator against a non insulator causes the build up of electrons which is known as static electricity, the electrons take the easiest route to earth, that's why if you touch any thing that is earthed you may get an electric shock :)
To make a positive ion, we need to remove one or more of the negative components from an atom. The negative charges that make up an atom are the electrons, which can be found in shells or orbitals some distance from the nucleus. Take away one or more electrons, and the protons, the positive charges that make up atoms and which hang out in the nucleus, give the atom an overall positive charge. An atom that has lost one or more electrons becomes a positive ion.
Electrons, for chemical reactions
Static charges can be removed by earthing. Since only negative charges can flow the earth takes in infinite number of electrons. This same principal is applied to a lightening conductor since lighting is nothing but the flow of electrons formed due to friction of two clouds.
An electron has the least binding energy and is therefore the easiest to remove. This occurs in everyday table salt.
Carbon.
Easiest way is to remove the bed. Then you can remove it without dropping the tank.

Electrons from an atom can be removed for ex. in a chemical reaction.
electrons
Positive ions.
The atom wants to have eight or full electrons in its outer valence ring... so if it has four electrons in its outer shell it has the choice of loosing four electrons or finding four electrons somewhere else (whichever is the easiest for it to bond with).
Easiest way to drain the radiator is to remove the lower coolant hose.
Particles
Add or remove electrons.
because metals have excess of electrons while non metals are electron deficient
