Statement 1 : The electrode may be negatively charged or positively charged, with respect to solution.Statement 2 : Metal atom of electrode has tendency to go into solution as ion and leave behind the electron at the electrode.

At electrode-electrolyte interface, there is a tendency of metal ion to deposit on metal electrode and make it positively charged. At the same time metal atom have tendency to go into solution as ions and leave behind the electrons at the electrode and make it negatively charged.
