Nuclear Chemistry Quiz

What is the main difference between chemical reactions and nuclear reactions?

• Chemical reactions involve particles within the nucleus, while nuclear reactions involve only the outermost electrons.

• Chemical reactions involve only new chemical compounds, while nuclear reactions involve the conversion of elements from one to another.

• Chemical reactions release or absorb immense amounts of energy, while nuclear reactions release or absorb relatively smaller amounts of energy.

• Chemical reactions are influenced by external factors, while nuclear reactions are not influenced by external factors.
