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 released a beta particle in a nuclear reaction.
Answer
Brief Explanations:
An alpha - particle is a helium nucleus with 2 protons and 2 neutrons. When an atom emits an alpha - particle, it loses 2 protons and 2 neutrons. Initially, the atom has 84 protons and 86 neutrons. After the reaction, it has 82 protons and 84 neutrons, which is a loss of 2 protons and 2 neutrons. Chemical reactions do not change the number of protons and neutrons in an atom's nucleus. Beta - particle emission changes a neutron to a proton or vice - versa without losing 2 protons and 2 neutrons simultaneously.
Answer:
It emitted an alpha particle in a nuclear reaction.
