What is a key difference between chemical and nuclear reactions? in chemical reactions, new compounds are formed. in nuclear reactions, compounds are destroyed. chemical reactions involve electron rearrangements. nuclear reactions involve changes to the nucleus. chemical reactions involve large changes in energy. nuclear reactions absorb or release small amounts of energy. in chemical reactions, only alpha radiation is emitted. in nuclear reactions, alpha, beta, and gamma decay may occur.

Answer;

Chemical reactions involve electron rearrangements. Nuclear reactions involve changes to the nucleus.

Explanation;

-Nuclear reactions involve a change in an atom's nucleus, usually producing a different element ,along with the emission of radiations like α, β and γ etc rays. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei.

-Different isotopes of an element normally behave similarly in chemical reactions as their extra-nuclear electronic configurations are same. The nuclear chemistry of different isotopes vary greatly from each other.

-Rates of chemical reactions are influenced by external effect like temperature,pressure and catalysts. Rates of nuclear reactions are spontaneous and are unaffected by such factors.

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!
