Question

question 1
what is the oxidation number of the following element? h₂

Explanation:

Step1: Recall oxidation rule for elements

For an element in its elemental form (like \( \text{H}_2 \), which is diatomic hydrogen, an elemental state), the oxidation number is 0.

Step2: Apply the rule to \( \text{H}_2 \)

Since \( \text{H}_2 \) is a molecule of hydrogen in its elemental form (not combined with other elements, just pure hydrogen), its oxidation number follows the rule for elemental substances.

Answer:

0
