Types of Radioactive Decay| Questions with 100 % Correct Answers | Verified

An atom that has 84 protons and 86 neutrons undergoes a reaction. At the end of the reaction, it has 82 protons and 84 neutrons. What happened to the atom? It accepted radiation in a chemical reaction. It donated neutrons to another atom in a chemical reaction. It emitted an alpha particle in a nuclear reaction. It accepted protons in a nuclear reaction. - NOT A Deuterium is an isotope of hydrogen. The nucleus of a deuterium atom consists of one proton and one neutron. When two deuterium nuclei fuse, helium-3 is formed, and a neutron is emitted. Which equation illustrates this process? - NOT B A What can form as a result of a chemical reaction? compounds isotopes alpha particles beta particles - A 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.
