Why do heavy elements neclei contain proportionally more neutrons than light element nuclei?
It is for this reason that large nuclei contain proportionally more neutrons than light elements
When two nuclei of light elements are forced together at extremely high temperature what happens?
They form heavier elements
What are the 3 main types of nuclear reactions?
Nuclear fission: When an element breaks apart to form lighter elements and other sub-atomic particles. Nuclear fusion: When two lighter elements fuse to form heavier ones.
What is the difference between fusion and fission atomic bombs?
Good question. A fusion bomb combines (fuses) light nuclei (hydrogen) into larger nuclei to get its energy. But it needs a fission bomb to start it. A fission bomb breaks up (fissions) heavy nuclei (uranium/plutonium) into smaller nuclei to get its energy.
Does solid citric acid react with light?
No, citric acid is stable in normal light.

Is it true that radioactive decay results in the fusion of stable nuclei along with the emission of multiple types of radiation?
No. Fusion is the combining of light elements into heavier elements (like 2 deuterium into 1 helium). radioactive decay is when you have an unstable atom releasing energy (and sometimes matter) in order to reach a more stable state.

How is nuclear energy in stars?
Stars obtain energy through the majority of their lives by the process of thermonuclear fusion of the nuclei of light elements to produce nuclei of heavier elements. Initially the processes fuses hydrogen nuclei, producing helium nuclei (similar to what hydrogen bombs do), but the process ceases when it produces nickel and iron nuclei at which point the star begins dying as it has run out of nuclear fuel.
What two 'light' elements have no stable nonradioactive isotopes?
The two elements are elements 43, Tc, technetium, and 61, Pm, promethium. Technetium has a few "nearly stable" isotopes with half-lives of over a million years. Promethium's longest lived isotope has a half-life of about 20 years.
What do your suprachiasmatic nuclei help you to detect?
light
What is The combining of light nuclei is called?
fusion
Alpha particles ejected from the nucleus travel at the speed of light?
No. Alpha particles are helium nuclei; such nuclei have a mass, and can therefore NOT travel at the speed of light.
How light elements and heavy elements formed differently?
The formation of the elements is a nuclear process that usually happens in stars. The core of the star is hot enough and has enough pressure to overcome the electric repulsion of the atomic nuclei and literally fuse the nuclei together. This process happens over and over again, but seems to stop at a certain mass. It appears that elements heavier than iron cannot be formed in the core of a star. These elements require more extreme conditions. The heavier elements on the Periodic Table (after Fe) are formed in supernova. These nuclei require tremendous energy to form, this energy must come from an event as large as a supernova.
What is the combining of light weight nuclei into heavier nuclei that gives off energy that fuels the Sun?
fusion
Who predicted gravitational bending of light?
Albert Einstein
What the combining of atomic nuclei is?
The combination of two light atomic nuclei to form a heavier nucleus is called fusion.
