Nuclear and Chemical Reactions

Nuclear reactions and chemical reactions have many differences and they have one main similarity, so I’m going to compare and contrast nuclear and chemical reactions.

Starting off nuclear reactions involve the nucleus of an atom. It’s the nuclear reaction that is made up of the composition of the nucleus changing and so the numbers of protons and or neutrons changes in a nuclear reaction.

Now the electrons are unaffected, so while the nucleus of the atoms are going through a nuclear reaction or changing the electrons orbiting the nucleus, remain the same, as the number of electrons orbiting the nucleus remains the same.

Then finally nuclear reactions can form different elements, so now we come to chemical reactions. Now as nuclear reactions involve the nucleus, chemical reactions involve electrons, particularly various electrons. In chemical reactions the atoms give, take and share various electrons. Now the nucleus and the rest of the atom is unaffected, but in particular, the nucleus isn’t affected. I want to drive home that point, because up here I talked about how nuclear reaction involves the nucleus, whereas the chemical reactions the nucleus is unaffected, instead focuses on electrons.

But with nuclear reactions the electrons are unaffected, so we have basically opposite directions going on here or the way the reaction takes place here, we have various types of reactions going on here or the way the reactions take place are opposite. Then chemical reactions cannot form new elements or cannot form elements, but chemical reactions can form compounds. In fact, basically, the products of the reaction are compounds. Those are the differences between nuclear and chemical reactions.

Now the main similarity is how they occur. Both nuclear reactions and chemical reactions can occur spontaneously or they can occur with the addition of energy. As you can see we have many differences here, but they both come about in the same way, either spontaneously or with the addition of energy.
