The atomic numbers of the 6th and 7th period elements related to ununoctium (Uuo), also known as oganesson, are crucial to understanding how we arrive at this noble gas.
To transition from radon (Rn), which has an atomic number of 86, to ununoctium (Uuo), which has an atomic number of 118, we need to fill an additional 32 electrons. This process involves filling the subshells in the following order: 6s, 5d, 6p, and finally the 7s, followed by 6d and 7p subshells.
The 6th period comprises elements from atomic numbers 87 (francium) to 112 (copernicium). The atomic numbers of the key elements in this period that fill the relevant subshells are as follows:
- Element with atomic number 87 (Fr)
- Element with atomic number 88 (Ra)
- Element with atomic number 89 (Ac)
- Elements from 90 (Th) to 103 (Lr) fill the 5f subshells
- Elements from 104 (Rf) to 112 (Cn) continue filling the 5d subshell
The 7th period includes elements from atomic numbers 113 (Nh) to 118 (Uuo). The 7th period elements fill the 7s, 6d, and 7p subshells, eventually culminating in the element with atomic number 118, ununoctium.
In conclusion, the atomic numbers of the 6th period elements that assist in reaching the noble gas ununoctium are significant as they are part of the electron filling process, which adheres to the principles of quantum mechanics and atomic structure.
