Oxidation, or the loss of electrons, will result in an element becoming positive. This element will show a(n) in oxidation number. Reduction, the gain of electrons, will cause an element to become positive and the element will show a(n) in oxidation number.

1)more

2) increase

3)less

4)decrease

Explanation:

Oxidation can be regarded as process involving loss of electrons when a reaction is taking place by an atom or molecule, atom as well as ion. Oxidation do take place as when there is increase in oxidation state of a molecule as well as atom or ion. Reduction which is opposite process takes place as a result of gain in electrons, or when there is decrease in oxidation state of an atom as well as molecule, or ion. Oxidation number gives the the number which is been allocated to elements during a reaction of chemical combination. It gives the count of sharable electrons for an atoms or electron it can gain or loose as chemical bonding is taken place.

It should be noted Oxidation, or the loss of electrons, will result in an element becoming more positive. This element will show an increase in oxidation number. Reduction, the gain of electrons, will cause an element to become less positive and the element will show a decrease in oxidation number.
