1.) what is the difference between fusion and a chemical reaction? explain in one sentence.

2.) describe what happens during a nuclear fusion reaction? explain in one sentence.

3.) which type of radioactive decay involves a helium atom? explain in one sentence.

1. Fusion involves the combination of atomic nuclei to form a heavier nucleus, while a chemical reaction involves the rearrangement of atoms to form new molecules.

2. During a nuclear fusion reaction, two atomic nuclei combine to form a single heavier nucleus, releasing a large amount of energy.

3. Alpha decay involves the emission of a helium atom, which consists of two protons and two neutrons, from a radioactive nucleus.

1) The difference between fusion and a chemical reaction is that fusion involves the merging of atomic nuclei to form a heavier nucleus, while a chemical reaction involves the rearrangement of electrons between atoms.

To get this answer, you need to understand the basic definitions of fusion and chemical reactions. Fusion refers to the process where atomic nuclei combine, releasing a large amount of energy in the process. On the other hand, chemical reactions involve the rearrangement of electrons between atoms, resulting in the formation or breaking of chemical bonds.

2) During a nuclear fusion reaction, two or more atomic nuclei come together to form a heavier nucleus, releasing a tremendous amount of energy due to the conversion of mass into energy, as described by Einstein's famous equation E=mc².

To answer this question, you need to have a basic understanding of nuclear fusion. It occurs within the incredibly high temperatures and pressures found in stars, such as our Sun, where lighter elements, like hydrogen, combine to form heavier elements, such as helium.

3) The type of radioactive decay that involves a helium atom is called alpha decay, where an unstable nucleus emits an alpha particle consisting of two protons and two neutrons, which is essentially a helium nucleus.

To answer this question, it helps to be familiar with the different types of radioactive decay. Alpha decay occurs when an atomic nucleus emits an alpha particle, which is made up of two protons and two neutrons. This process reduces the atomic number of the nucleus by two and the mass number by four, effectively forming a helium atom.

1.) The difference between fusion and a chemical reaction is that fusion involves the combining of atomic nuclei to form a new element, while a chemical reaction involves the rearrangement of atoms to form different molecules or compounds.

2.) During a nuclear fusion reaction, two atomic nuclei combine under high temperatures and pressures to form a heavier nucleus, releasing a large amount of energy in the process.

3.) The type of radioactive decay that involves a helium atom is alpha decay, wherein a radioactive nucleus emits an alpha particle consisting of two protons and two neutrons.
