Question

The periodic table is broken down into rows and blocks such as the s, p, d and f blocks. Each block has different properties associated with them. It has been hypothesized that we could eventually reach a “g” block if enough elements were created.Hypothesize what kinds of properties a “g” block element would have. Would it be stable? Radioactive? What would its radius be like? Please explain your reasoning in 200 - 250 words.

Answer 1

If g-block is introduced in the periodic table then it elements will start from 8^th period of the periodic table. We know that the properties of elements depend more on the group than of periods. So, properties of these elements depend on which group they are belonging or the subshells act in that period. It has been noted that the elements beyond the actinides have less studied due to their radioactive nature. Hence these elements also show the radioactivity properties. Due to the radioactive nature, these elements are not so stable in nature. We cannot able to predict the properties of g-block elements; we only have to apply the theoretical approximation to study their properties. All the elements of the g-block show metallic bond. These elements show metallic character and form metallic radii most likely to the metallic radii of main group alkyl and alkyl earth metal. Due to the relativistic effect, the elements of g-block are almost same in size.

According to the Glenn Seaborg “Island of stability”, It has been found that the elements beyond the 7^th period are unstable and radioactive in nature.

In conclusion, we can say that the elements of 8^th period will be less explored in future also due to their unstable and radioactive nature. We also cannot able to predict the properties of these elements.
