Explanation:
electrodes are the rods ( graphite) through which electric current is passed this process is called as electrolysis process
anode means negative charge
cathode means positive charge
Na-11(at no.)
looses one electron from its outermost shell to get octet configuration as Neon-10 and forms Na+
Cl-9
gains one electron to get octet configuration as neon 10 and forms Cl-
now
Na+ + Cl- gives rise to NaCl
NaCl is commonly used in our daily life which is called as SALT
