When an object gets negatively charged by the process of friction, then:
(a) the object loses some electrons (b) the object loses some protons
(c) the object gains some electrons (d) the object gains some protons
If an object made of substance A is rubbed with an object made of substance B, then A becomes positively charged and B becomes negatively charged. If, however, an object made of substance A is rubbed against an object made of substance C, then A become negatively charged. What will happen if an object made of substance B is rubbed against an object made of substance C?
___ are formed when atoms lose or gain electrons.
