The heaviest elements come mainly from supernovae. Iron is the heaviest element that can be produced by fusion. Heavier elements are produced by neutron capture. An individual free-floating neutron collides with a nucleus and merges with it. That doesn't produce a higher element on the Periodic Table, because the atomic number depends on the number of protons. However, nuclei with too many neutrons are unstable, and will eventually "decay". A neutron will decay into a proton and an electron.
Free neutrons don't exist in great numbers in normal stars, so neutron capture doesn't happen significantly in them.
Elements from carbon to iron can be formed by fusion in large stars.
What else can I help you with?
Is the gas around a planetary nebula helium?
The amount of helium compared to other elements differ but a nebula occurs so late in a stars lifetime that heavy elements have been synthesized. A nebula is thus often a complex combination of several elements mostly between helium and iron.
What happened to the heavy elements in the proto earth?
Heavy elements in the proto Earth sank towards the core due to their higher density, leading to the differentiation of the Earth into layers based on element composition. This process is known as planetary differentiation and played a key role in shaping the Earth's interior structure.
How do we get heavy elements?
Heavy elements were formed in stars, and blown out into space in supernova explosions.
Why do objects sink?
objects sink because they are to heavy.
Where did heavy metal originate for example what year?
1968.
What do red giants and supernovas play in the production of future stars?
Red giants - As they near the end of their life they will "shed" their outer layers, returning material back into the Universe as a planetary nebula.Supernova - they seed the Universe with heavy elements - metallicity, which when formed into "newer" stars has the effect of making them "burn" slower.Supernova are also one manner in which dust clouds get that "nudge" to start forming protostars.
What are super heavy elements?
Super heavy elements are elements with atomic numbers greater than 104. They are synthetic and do not occur naturally on Earth. These elements are typically produced in laboratories through nuclear reactions involving heavy isotopes.
What would be considered heavy objects?
Heavy objects are generally those that are difficult to lift or move without assistance, typically weighing more than 50 pounds. Examples of heavy objects include furniture, appliances, machinery, and equipment.
What planet contains the fewest heavy element?
Jupiter contains the fewest heavy elements. Unlike other planets, Jupiter is a gas planet, and contains mostly light elements.
Why is it hard to move heavy objects fast?
Moving heavy objects fast requires greater force, which can be difficult to generate quickly. Additionally, overcoming inertia and friction for heavy objects takes more effort and energy. Inadequate grip, balance, or coordination can also make it challenging to move heavy objects quickly without risking injury.
How do you measure heavy objects such as automobile?
Pounds
Why do objectes?
objects sink because they are to heavy.
