Question

When in a compound, the oxidation number of a nonmetal:

is always fixed and can never be changed

can only be deduced once all the other oxidation numbers in the equation are totaled

may depend on what other elements are in the compound

must remain the same on both sides of the equation

Answer 1

May depend on what other elements are in the compound

Step-by-step explanation:

• A compound is made up of atoms from different elements. For example, water is a compound made up of hydrogen atoms and oxygen atoms.
• The oxidation number is the number showing the charge of an atom. it can be positive, zero or a negative value.
• The oxidation number of an atom in a compound depends on atoms of other elements in the compound.
• For example, the oxidation number of Nitrogen in HNO₃ is +5 and in NH3 is -3.
