How can you tell if an element has been reduced? A. The number of its electrons has not changed in the reaction, B. It has a positive oxidation state in the product, C. It has more electrons in the product than in the reactant, D. It has fewer electrons in the product than in the reactant.​

C. It has more electrons in the product than in the reactant

Explanation:

A type of reaction is called REDOX or oxidation-reduction reaction. In this reaction, substances (element or compounds) involved are either oxidized or reduced. To be oxidized means that a substance has lost electrons and hence, have a positive oxidation state in the product side.

On the other hand, reduction means that the substance has gained or accepted electrons, and hence has a reduced oxidation state in the product side. In other words, a reduced element will have more electrons in the product than in the reactant.

For example, in the following equation:

A + B = A- + B+

A is said to be reduced because it has more electrons (1) in the product than in the reactant (0).

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
