The Coulomb law itself is easy to understand; but I don't think that the "why" has an easy answer, which I think is what you are after. The reason - if it is known at all - probably involves some complicated quantum mechanics.
There are several types of chemical bonds. An ionic bond, for example is when two elements have opposite charges are attracted to each other. A positive and a negative charge or a negative and a positive charge can be attracted to each other. If a positive and a positive are attracted to each other or a negative and a negative are attracted, that's considered an immoral bond.
There is a negative and positive charge between the clouds or the sky and the ground. The positive charge is attracted to the negative. So positive begins to charge up before basically attacking the negative which is the ground.
positive charges
A negative point charge will be attracted towards a positive point charge in an electric field.
Electrons have a negative charge and are attracted by the positive end.
Electrons have a negative charge and are attracted by the positive end.
When a positive and negative charge collide, their forces act in the same direction, from positive to negative. As a result, contrary charges are attracted to one another: the electric field and forces produced by two electrical charges of opposite polarity. Both charges are attracted to each other.
Electrons would be attracted to a proton due to their opposite charges. The positive charge of the proton exerts an attractive force on the negatively charged electron, causing them to be attracted to each other.
Electrons have a negative charge and are attracted by the positive end.
it would be probably cation as it carries a positive charge in electrolysis and is attracted towards negative electrode
Electrons have a negative charge and are attracted by the positive end.
Protons, which have positive charge, attract electrons, which have negative charge. Also, quarks with positive charge attract quarks with negative charge. (Actually, it is this electric charge which defines the properties of the particle they make up. A proton has more quarks with positive charges than with negative charges, for example.)
