Answer:
Group of the Daughter Element
The resulting daughter element would belong to Group 4 of the periodic table.
Explanation
Radioactive decay is a process in which a nucleus of an atom changes into another element by emitting particles or radiation. The type of radiation emitted depends on the type of decay. Alpha decay is a type of radioactive decay in which a nucleus emits an alpha particle, which is a helium nucleus consisting of two protons and two neutrons.
In this case, the nucleus of an alkaline earth metal undergoes radioactive decay by emitting three alpha particles in succession. This means that the original nucleus loses six protons and six neutrons, resulting in a new element with an atomic number four less than the original element.
Alkaline earth metals belong to Group 2 of the periodic table, which includes elements such as magnesium, calcium, and strontium. When an alkaline earth metal nucleus undergoes alpha decay, the resulting daughter element will have an atomic number four less than the original element and will therefore belong to Group 4 of the periodic table.
Group 4 of the periodic table includes elements such as carbon, silicon, and titanium. These elements have four valence electrons and are known for their ability to form stable covalent bonds with other elements.
Conclusion
In conclusion, the daughter element resulting from the radioactive decay of an alkaline earth metal nucleus by emission of three alpha particles in succession would belong to Group 4 of the periodic table. This is because the new element will have an atomic number four less than the original element and will therefore have similar chemical properties to other Group 4 elements.
