Elements larger than 10 protons are primarily formed through nuclear fusion in stars, where lighter elements combine under extreme temperature and pressure. In massive stars, fusion processes can create heavier elements up to iron through successive fusion reactions. Elements heavier than iron are typically produced in supernova explosions or neutron star mergers, where the intense energy allows for rapid neutron capture processes (r-process) and other nuclear reactions to occur. These processes contribute to the cosmic abundance of heavier elements in the universe.
What else can I help you with?
Why are elements larger than element 82 rafioactive?
Elements larger than element 82 (lead) are considered radioactive because they have unstable nuclei due to an excess of protons and neutrons. This instability leads to radioactivity as these elements undergo radioactive decay to achieve a more stable configuration. The strong nuclear force, which holds the nucleus together, becomes less effective as the number of protons increases, causing larger atoms to be more prone to decay. As a result, heavier elements emit radiation in the form of particles or electromagnetic waves as they transform into more stable isotopes.
Is a proton larger or smaller than an electron?
Protons have a larger mass, but it is unclear which (if either) have a larger radius. The electron does not seem to have ANY measurable radius.
Why do atoms of heavier elements generally contain more neutrons than protons?
because the protons and electrons HAVE to cancel out each other and ive knowtest that normally, there are around 1/2 as many neutrons then protons.
If there is a difference between a substance's atomic number and its atomic mass and which measure must be the larger number?
The atomic number represents the number of protons in an atom, while the atomic mass represents the sum of protons and neutrons. Generally, the atomic mass is larger than the atomic number for most elements since it includes both protons and neutrons.
What has more protons carbon or copper?
Copper has more protons than carbon. Carbon has 6 protons, while copper has 29 protons. This difference in the number of protons is what distinguishes the two elements on the periodic table.
Which element has the largest amount of protons and is not man made?
The element with the largest amount of protons that is not man-made is uranium, with 92 protons. All naturally occurring elements with more protons than uranium are only found in laboratories as synthetic elements.
Are electrons larger than neutrons and protons?
no. protons and neutrons are MUCH larger than electrons.
Elements with more than 92 protons are called?
Elements with more than 92 protons are called Transuranic elements.
Are protons bigger than neutrons?
Yes, neutrons are larger than protons.
How were chemical elements larger than helium made?
This process is called stellar nucleosynthesis.

These elements form ions because they have more than?
protons than electrons
Is a proton larger or smaller than an electron?
Protons have a larger mass, but it is unclear which (if either) have a larger radius. The electron does not seem to have ANY measurable radius.
What elements have more than 92 protons in their nuclei?
radioactive.
What are elements with more than 92 protons called?
Transuranic.
Nonmetal ions larger than their elemental counterparts?
Non metallic ions are negatively charged. They have more electrons than protons. So they are larger than elemental counterparts that have equal number of protons and electrons.
Why do atoms of heavier elements generally contain more neutrons than protons?
because the protons and electrons HAVE to cancel out each other and ive knowtest that normally, there are around 1/2 as many neutrons then protons.
