Which element has the electron configuration [rn] 7s2 5f14 6d4 ?

The element with the electronic configuration of  [Rn] 7s² 5f¹⁴ 6d⁴ is seaborgium

From the question given above, the following data were obtained:

Electronic configuration => [Rn] 7s² 5f¹⁴ 6d⁴

Next, we shall determine the atomic number of the element. This can be obtained as follow:

Radon, Rn has atomic number of 86.

Thus, the atomic number of the element will be the sum of the atomic number of radon and the remaining electrons in the electronic configuration of the element i.e

Atomic number of element = 86 + 2 + 14 + 4

Finally, we shall determine the name of the element.

Atomic number of element = 106

Comparing the atomic number of the element (i.e 106) with those in the periodic table, the name of the element is Seaborgium, Sg

Therefore, the element with the electronic configuration of  [Rn] 7s² 5f¹⁴ 6d⁴ is Seaborgium.
