Oxidation numbers up to +7 is possible. For example: +7 for Cl in HClO4 or Cl2O7. +6 for S in SO3 or H2SO4 +5 for N in HNO3 or N2O5 +4 for C in CO2
+1 for H -2 for O +5 for N
-3
The oxidation numbers in PO43- , phosphorus oxidation number=+5; oxygen = -2
There are two oxidation numbers. P shows +5 oxidation number.
The oxidation state of N in HNO3 is +5. Oxygen is -2 and H is +!.
No. HNO3 already has hydrogen and nitrogen in their highest possible oxidation states.
Oxidation numbers up to +7 is possible. For example: +7 for Cl in HClO4 or Cl2O7. +6 for S in SO3 or H2SO4 +5 for N in HNO3 or N2O5 +4 for C in CO2
5+
sum is zero. +1 for H, +5 for N, -2 for each O. So sum is zero
+1 for H -2 for O +5 for N
-3
The oxidation numbers in PO43- , phosphorus oxidation number=+5; oxygen = -2
There are two oxidation numbers. P shows +5 oxidation number.
It shows some oxidation numbers. Generally it shows +4 oxidation numbers.
No, the can only have positive oxidation numbers
All metals have positive oxidation numbers. Non-metals may have positive or negative oxidation numbers and some metalloids have both positive and negative oxidation numbers as well
