Answer:
sorry , there is nothing called mono valency.
it is just valency.
to find valency of sodium :
Na atomic no. = 11
no. of electrons = The atomic no.
hence no. of electrons = 11
now , ec (electronic configuration) = 2,8,1
as the m shell contains 1 election in excess that is preventing the atom to become an octet state atom.
the valency = +1
