It would then seem logical that the fourth type, if it followed the same pattern, would be the strongest of them all.

But what if you discovered that the fourth type was weaker than the third, despite belonging to the same family? This is what happened at the atomic level with an ultra-heavy element called "Seborgium," as a scientific experiment revealed that the effects of Einstein's theory of relativity can overturn expectations about the strength of chemical bonds.
The element "Seborgium", which has the atomic number 106, does not exist practically in nature. Rather, it is produced inside particle accelerators, and in very small quantities. Production may not exceed a few atoms per day, and its atoms decay radioactively in less than a second in some cases.
However, researchers from the GSI Heavy Ion Research Center and the FAIR facility in Germany, in a study published in the journal Nature, succeeded in detecting 75 atoms of it, to study its ability to form a chemical bond with carbon monoxide molecules.
The experiments conducted by the researchers began with the production of "Seborgium" atoms, as they used a particle accelerator to produce those atoms that do not live long and decay quickly.
The researchers then exposed the cyborgium atoms that produced carbon monoxide gas to see if each atom would be able to bond with six molecules of the gas to form a specific chemical compound called "cyborgium hexacarbonyl".
The third step was to track the atoms that succeeded in forming the compound. They passed the reaction products through two reagents. The desired compound could reach the second reagent, while other products were deposited on the first reagent.
Then, the researchers compared the results with the element tungsten. Out of 75 seaborgium atoms they observed, three atoms reached the second reagent in the form of the desired compound. In the tungsten experiment, the similar compound may have formed in 17% of the observed atoms.
Based on these results, scientists concluded that the bond strength in the seborgium compound is about four kilojoules per mole less than that in the tungsten compound, as a result of the expected trend of bond strength fluctuating in this chemical group of the periodic table.
Not content with discovering that the chemical bond in seaborgium was weaker than expected, the researchers looked for the reason and found that calculations that took into account the effects of Einstein's relativity explained this weakness, while calculations that ignored them were wrong and predicted that the bond would continue to grow stronger.
The result reveals that the similarity between elements in the periodic table does not necessarily mean that they will behave in the expected way. In superheavy elements, relativity affects the movement and distribution of electrons within the atom, which may change the way they bond with other elements.
