Answer :
Final answer:
Brzykium-116 does not exist and thus does not have a relative abundance. Elements such as livermorium have an atomic number of 116 but are synthetic and have no natural relative abundance. Lead, with a stable isotope near mass 116, has a well-known abundance.
Explanation:
The element referred to as brzykium-116 does not exist; it appears to be a typographical error or a fictional name. Therefore, there is no information on the relative abundance of brzykium-116. However, looking at the periodic table information provided, we can talk about elements with atomic numbers close to 116, like livermorium (Lv) with an atomic number of 116.
Livermorium is a synthetic element, and it does not occur naturally in the environment. Thus, it does not have a natural relative abundance; it can only be created in very tiny amounts in particle accelerators through highly specialized nuclear reactions.
Similarly, for nuclei around mass number 116, we have bismuth-209 as the most stable isotope and lead (Pb) with a stable isotope of mass number 207. If the student is querying about a nearby element with a mass close to 116, these would be relevant, especially lead as it has stable isotopes and a well-known abundance.
