Why do heavy elements neclei contain proportionally more neutrons than light element nuclei?
Heavy elements contain more protons, which repel each other due to their positive charge. Neutrons help stabilize the nucleus by adding nuclear binding energy without adding additional electrostatic repulsion like protons do. Therefore, heavy nuclei tend to have more neutrons to help balance out the increased number of protons.
Radioactive elements include all those elements whose nuclei contain what?
Radioactive elements include all elements whose nuclei either:contain protons more than 83 proton, orcontain neutron to proton ratio out of the stability ratio.refer to related question below.
Elements with more than 92 protons are called?
Elements with more than 92 protons are called Transuranic elements.
What describes all the nuclei with more than 83 protons?
Nuclei with more than 83 protons are considered to be heavy or high atomic number elements. They are generally unstable because the electrostatic repulsion between the positively charged protons can overcome the strong nuclear force holding them together, leading to radioactive decay. These elements are typically man-made through processes such as nuclear fusion in laboratories.
Why is the number of electrons more than nucleus in the sea of electrons model?
In any neutral object the number of electrons is equal to the number of protons. All metallic elements contain more than one proton in the nucleus. Therefore there will be more electrons than atomic nuclei.
Are the nuclei of final elements produced by nuclear decay more stable or less stable than the nuclei of original radioactive elements?
Of course they are more stable, therefore they formed naturally.
Heavier nuclei have more neutrons than protons?
Yes, heavier nuclei tend to have more neutrons than protons. This is because the strong nuclear force, which holds the nucleus together, helps balance the electrostatic repulsion between positively charged protons. Having more neutrons helps stabilize the nucleus by increasing this attractive force.
What are elements with more than 92 protons called?
Transuranic.
These elements form ions because they have more than?
protons than electrons
How are elements with nuclei larger than iron nuclei formed?
Supernova form heavier elements
Why those elements does not emit radiation whose atomic number is less than 82?
Elements with atomic numbers less than 82 do not emit radiation because they do not have unstable nuclei. Radioactive decay occurs when an atom has an unstable nucleus, which may be due to an imbalance of protons and neutrons. Elements with atomic numbers greater than 82 are more likely to have unstable isotopes that can undergo radioactive decay.
Which element has two or more protons than carbon?
Nitrogen has one more proton than carbon with 7 protons.
