What elements are beyond lead?
Q: What elements are beyond lead?
A: The elements beyond lead are radioactive and do not have stable isotopes.
Q: What is the theory in physics that explains why some elements have longer half lives?
A: The theory in physics states that after a number of elements with short half lives, there will be others with longer half lives, known as Islands of Stability. This is because when the number of neutrons and protons completely fill the energy levels of a given shell in the nucleus, the binding energy per nucleon will reach a local maximum and thus that particular configuration will have a longer lifetime than nearby isotopes.
Q: What are magic numbers for spherical nuclei?
A: Magic numbers for spherical nuclei are neutron numbers of 184 and proton numbers of 114, 120 and 126. These would mean that the most stable spherical isotopes would be flerovium-298, unbinilium-304 and unbihexium-310.
Q: Is Hassium-270 believed to be doubly magic?
A: Yes, Hassium-270 is believed to be a doubly magic deformed nucleus, with deformed magic numbers 108 and 162.
Q: How long is its half life?
A: Its half life is 3.6 seconds.
Q: Are there any practical applications for these elements?
A: Yes, if they have isotopes with adequate lifespans they could potentially be used for various practical applications such as particle accelerator targets or as neutron sources.
