What is the oxidation number of sulfur in na2s2o3?
(1) -1 (3) +6
(2) +2 (4) +4

Na (sodium) = +1

O ( Oxygen) = - 2

S ( Sufur) = + 2

Answer (2)

hope this helps!

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
