Answer:
+4
Explanation:
Hello,
In this case, considering nitrogen dioxide's formula:
And due to the fact that oxygen's oxidation state is -2 in this case, we could find nitrogen's oxidation state in nitrogen dioxide by using a balance charge:
For that reason, nitrogen's oxidation state is +4:
Best regards.
It is rinsed with ionised water to remove any impurities that may be present
I believe it is E because Cesium has the most electrons, protons, and neutrons.
