Chapter 7: Problem 105

Element 106 has been named seaborgium, \(\mathrm{Sg}\), in honor of Glenn Seaborg, discoverer of the first transuranium element. a. Write the expected electron configuration for element 106 . b. What other element would be most like element 106 in its properties? c. Write the formula for a possible oxide and a possible oxyanion of element 106 .

Short Answer

Expert verified
a. The electron configuration for element 106 (Seaborgium, Sg) is: \(1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}5s^{2}4d^{10}5p^{6}6s^{2}4f^{14}5d^{18}6p^{6}7s^{2}5f^{14}6d^{4}\) b. Tungsten (W) has a similar electron configuration and is also in group 6, so it is expected to have similar properties to Seaborgium. c. The possible oxide for Seaborgium would be SgO3, and the possible oxyanion would be SgO4^(2-).

Step by step solution

01

a. Electron configuration

To find the electron configuration for element 106 (Seaborgium, Sg), we need to distribute the 106 electrons among the available subshells. The order to fill the subshells is given by the following sequence: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d We can stop after filling the 6d subshell since it covers 106 electrons. The electron configuration is: \[1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}5s^{2}4d^{10}5p^{6}6s^{2}4f^{14}5d^{18}6p^{6}7s^{2}5f^{14}6d^{4}\]
02

b. Similar element

An element with similar properties to Seaborgium would belong to the same group in the periodic table. Since Seaborgium has 6 electrons in its last d subshell, it belongs to group 6. Tungsten (W) has a similar electron configuration and is also in group 6, so it is expected to have similar properties to Seaborgium.
03

c. Possible oxide and oxyanion

To predict the oxide and oxyanion for Seaborgium, we need to consider its typical oxidation state. Element of group 6 generally have an oxidation state of +6. So, the possible oxide would be SgO3 and the possible oxyanion would be SgO4^(2-).
