What do you think nuclear chemists mean when they say that 8 20 and 50 are magic numbers for isotopes?
It is simply that among period 2 elements, oxygen (8) is one of the elements which has the largest number of isotopes, among period 4 elements, calcium (20) has the largest number of isotopes, and among period 5 elements, tin (50) has the largest number of isotopes. In fact tin has the largest number of isotopes overall.

Who are or what is the name called alchemist?
Alchemists were the first chemists. Yet they used magic along with their chemicals.
Why are chemical equations important in chemistry?
The alchemists were the first chemists. They mixed chemicals, but also believed that magic would help them in their experiments and formulas. It didn't. But their chemical experiments eventually led to the science of chemistry.
The stability of a nucleus depends on the?
most of the atoms under atomic number 20 have a 1:1 neutron to proton ratio the ratio goes up, but not by much, and will show a "band of stability" for all atoms some isotopes exist with the number of neutrons outside this band, which makes those atoms (those isotopes of those atoms) unstable. unstable nuclei leads to radioactivity, when the nucleus releases particles and energy to gain a more stable ratio of neutrons to protons. radioactivity is usually toxic to most living things (not cockroaches believe it or not!)
Factors that brought about the development of chemistry from alchemy?
The alchemists were the first chemists. They mixed chemicals, but also believed that magic would help them in their experiments and formulas. It didn't. But their chemical experiments eventually led to the science of chemistry.
What is the difference between alchemists and scientists?
Alchemists believed in magic. Scientists don't. The alchemists were the first chemists. But in addition to mixing chemicals, they also believed that magic would help with their experiments and formulas. It didn't. But their experiments led to the development of the science of chemistry.
What role do magic numbers play in nuclear physics?
Magic numbers in nuclear physics refer to specific numbers of protons or neutrons that result in increased stability of atomic nuclei. These magic numbers play a crucial role in determining the properties and behavior of atomic nuclei, such as their binding energy and nuclear structure. They help explain why certain elements are more stable than others and are important for understanding nuclear reactions and the stability of isotopes.
Where are the band ' The magic numbers' from?
The Magic Numbers are from London, England.

Why magic numbers in nuclear physics are called magic?
They are considered magical because historically, when the elements at these atomic numbers were observed, they seemed to have extraordinary stability than what the usual binding energy curve showed. If you are asking about the word "magic", it was a term coined by Wigner because he found this idea of shells too amazing but true.
Merits of nuclear shell models?
Nuclear shell models provide a useful framework for understanding the structure of atomic nuclei based on the organization of nucleons into energy levels, similar to electron shells in atoms. They successfully predict the magic numbers of stable nuclei and the nuclear binding energies. Additionally, shell models contribute to our understanding of nuclear properties such as spin, parity, and magnetic moments.
