A body can be negatively charged by
Giving excess of electrons to it
Removing some electrons from it
Giving some protons to it
Removing some neutrons from it
Excess of electron gives the negative charge on body.
When some electrons are removed from an uncharged body, it
Lithium is a metal whose electronic configuration is 2 and 1 including 3 protons 3 electrons and 3 neutrons. So, if we remove 1 electron from lithium to make it stable. Then ,why would we call it lithium as it has 3 protons 3 electrons and 3 neutrons. But , after removal of 1 electron only 2 electrons are left. So, why would we call it lithium then.
If an atom gains an electron, shouldn't it be positively charged since it might now want to give away its extra electron. But it is also considered to be negatively charged due to presence of excess electrons
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
