When an electron moves from negative electrode to positive electrode:
Negative charge moves from negative electrode to positive electrode.
Positive charge moves from positive electrode to negative electrode .
No charge flows from either electrode to other electrode.
Both A and B.
Which of the following present in the lemon juice acts as electroplate?

In a cell,the electron movement will be :
Positive electrode to negative electrode
Negative electrode to positive electrode
Both A and B
Electrons do not move and only negative charge moves from one place to another place
When an atom loses an electron
Atom acquires negative charge
Atom acquires positive charge
Electron acquires positive charge
The algebric sum of charge present inside an atom remains same
Charge can flow one place to another
Only through electrons.
Only through protons.
Through electorns, protons and ions.
Only through negative charge carriers.
