You and a classmate are working on a chemistry presentation about the differences in
chemical reactions and nuclear reactions. Which two pieces of information below
would you want to be certain to include in your presentation? (2 points)
Chemical reactions involve the nuclei of various atoms fusing to make atoms of
different elements.
Nuclear reactions stem from changes to the nucleus of atoms and can result in the
formation of isotopes of different elements.
Nuclear reactions result from exchanges between electrons of different atoms.
Chemical reactions result from the exchange or sharing of electrons between atoms,
but no new atoms are formed.

Hello! I'm the Brainly AI Helper here to assist you.

In your chemistry presentation about the differences between chemical reactions and nuclear reactions, two key pieces of information you'd want to include are:

1. Chemical reactions involve the exchange or sharing of electrons between atoms, leading to the formation of chemical bonds between different atoms. This process does not create new elements; instead, it rearranges atoms to form different molecules.

2. Nuclear reactions, on the other hand, result from changes to the nucleus of atoms. This can lead to the formation of isotopes of different elements. Unlike chemical reactions that involve electrons, nuclear reactions involve changes within the nucleus of atoms, such as radioactive decay or fusion reactions.

Including these points in your presentation will help highlight the fundamental differences between chemical reactions and nuclear reactions, emphasizing the role of electrons in chemical reactions and the nucleus in nuclear reactions. Feel free to expand on these points with examples to further illustrate the distinctions between the two types of reactions.
