Step 1:
Write down Chemical formula, Overall compound is neutral, so overall charge on it is zero,
Na₃AsO₂ = 0
Step 2:
Write down the oxidation state of known elements, i.e O.S of Na is +1, and O.S of O is -2, Now put these values in above formula.
(+1)₃ + As + (-2)₂ = 0
Step 3:
Now solve for As,
(+1)₃ + As + (-2)₂ = 0
+3 + As - 4 = 0
As = 4 - 3
As = +1
Result:
Oxidation state of Arsenic in Na₃AsO₂ is +1.

Sorry don’t understand the last question
Answer:
Ionic compounds don't conduct electricity very well because the charge carriers can't move through the crystal. They can conduct heat because the kinetic energy itself is the "heat carrier”.
Hope this helps :)
Answer:
An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. ... The nucleus of an atom contains protons and neutrons
