These are called  protons, electrons and neutrons.  They are very different from each  other in many ways. One way they are different is their "charge."   Protons have a positive  (+) charge. Electrons have a  negative  (-)   charge.  Neutrons have  no charge.   [/SIZE][/SIZE] [SIZE=-1][SIZE=+1]Usually, atoms have the  same number of electrons and protons.  Then the atom has no charge, it  is "neutral." But if you rub things together, electrons can move from  one atom to another.  Some atoms get extra electrons.  They have a  negative charge.  Other atoms lose electrons.  They have a positive  charge. When charges are separated like this, it is called static  electricity.    [/SIZE][/SIZE] [SIZE=-1][SIZE=+1]If two things have  different charges, they attract, or pull towards each other.  If two  things have the same charge, they repel, or push away from each other.

Now  each of the hairs has the same positive charge.  Things with the same  charge repel each other.  So the hairs try to move away from each other.   The farthest they can get is to stand up and away from all the other  hairs.
