The electrons still rotate around the nucleus due to the attraction force between the protons in the nucleus and electrons. The electrons may leave the atom and move freely due to the weakness of...
Secondary Cells are characterized by reversible chemical reactions, These cells can be recharged by passing an electric current from external source between their poles in a direction opposite to the discharge process, Secondary Cells...
A hydrogen electrode is used as a standard electrode in measuring the electric potential of other electrodes because its potential equals zero, the standard hydrogen potential is not equal to zero in some cases...
Electrochemistry is a branch which is interested in studying the exchange conversion of chemical energy and electrical energy through oxidation & reduction, Electrochemistry means chemistry of electrons because the electrons transfer from one point...
