Question

What is the atomic number of the element \[ununnilium\] ?

Answer 1

Hint: The name \[ununnilium\] is a systematic name given to an element having a high atomic number. The element is yet to be discovered and has therefore been named according to a set of rules. Even though the element has not been discovered, its position in the modern periodic table is reserved on the basis of its atomic number. Its electronic configuration based on its atomic number suggests that it is part of the extended periodic table.

Complete answer:
Each element in the modern periodic table has a fixed position depending upon its atomic number and electronic configuration. The elements are arranged in an increasing order of their atomic numbers which is the total number of protons present inside their nucleus.
Uranium is the heaviest stable atom known and all elements placed in the modern periodic table beyond uranium are very unstable and have short life times. These elements are sensitive towards radioactive decay. Thus the series of elements with atomic number higher than Uranium is known as transuranic series.
Many members of the transuranic series are yet to be discovered and have only been predicted. The elements are given a name only after their discovery. These hypothetical elements are named according to the systematic naming of transuranic elements. Each digit of the atomic number is translated into a Latin or Greek word that is a numerical root.
The method of translating the Greek or Latin symbol into a number is as follows:
\[0 = nil\]
\[1 = un\]
\[2 = bi\]
\[3 = tri\]
\[4 = quad\]
\[5 = pent\]
\[6 = hex\]
\[7 = hept\]
\[8 = oct\]
\[9 = enn\]
Thus, the element \[ununnilium\] has the atomic number \[110\]

Note:
The atomic number of \[ununnilium\] suggests that it would belong to the transactinide of the d-block elements. The position predicted for this element in the seventh period and the tenth group. Its properties are expected to be similar to that of nickel, palladium and platinum.
