What stellar event produced elements with atomic masses greater than iron?
Supernova explosions are responsible for producing elements with atomic masses greater than iron through nucleosynthesis processes. During these violent events, heavy elements are forged from lighter elements through rapid fusion reactions.
How are elements with atomic masses greater than uranium made?
Elements with atomic masses greater than uranium are typically produced in supernova explosions, where high-energy processes enable the fusion of heavy nuclei. This process can lead to the creation of transuranic elements such as neptunium, plutonium, and beyond. Additionally, elements beyond uranium can also be artificially synthesized in particle accelerators through nuclear reactions involving target nuclei.
What did Dimitri Mendeleeve do?
Dmitri arranged the elements in order of increasing atomic masses. He arranged elements in rows and columns according to atomic masses.
When masses combine to form elements with larger masses?
Atomic fusion occurs when masses combine to form elements with larger mass.
What elements have such small masses that they are not even considered when atomic masses are calculated?
Electrons
Do all elements have different atomic masses?
yes
Why aren't atomic masses of elements not whole numbers?
because of its no. in table of elements
Name the elements whose atomic masses corrected by mendeleev?
The atomic masses corrected by Mendeleev are those of beryllium, indium, and uranium. Mendeleev was able to accurately predict the properties of these elements based on their corrected atomic masses.
What neighboring elements have atomic masses out of order?
Tellurium and Iodine
What two elements have the smallest atomic masses?
hydrogen and lithium
Where was mendeleev's strategy for classifying elements was modeled on?
Atomic Masses
How were the atomic number and the atomic masses of the elements determined?
Atomic masses are determined by mass spectrometry. The atomic number is identic with the number of protons in the atom - depends on position in the periodic table.
