Question

What is the condensed electron configuration for u?

Answer 1

The condensed electron configuration for uranium (U) is [Rn]
`5f^ 6d^1`
`7s^2`.

Step-by-step explanation:

The electron configuration of an atom describes the distribution of its electrons in various orbitals. Uranium (U) has an atomic number of 92, meaning it has 92 electrons.

To determine the condensed electron configuration, we use the noble gas shorthand, which involves representing the configuration of the noble gas that precedes the element in square brackets, followed by the remaining electron configuration.

For uranium, the noble gas preceding it is radon (Rn), which has the electron configuration [Xe] 4f14 5d10 6s2 6p6. Using this, we add the electron configurations of the subsequent orbitals for uranium. The 5f sublevel accommodates 14 electrons, the 6d sublevel holds 10 electrons, and the 7s and 7p sublevels together hold 2 + 6 = 8 electrons.

Putting it all together, we get [Rn] 5f3 6d1 7s2 as the condensed electron configuration for uranium.
