Which element falls under the electron configuration [Xe] 4f^14 5d^10 6s^2 6p^1?

The electron configuration [Xe] 4f^14 5d^10 6s^2 6p^1 corresponds to the element thallium (Tl). This configuration indicates that it has filled 4f and 5d orbitals along with partially filled 6s and 6p orbitals.

To break down the configuration:

• The notation [Xe] indicates that the element has the same core electron configuration as xenon, which accounts for the first 54 electrons.

• The 4f^14 part signifies that there are 14 electrons in the 4f subshell, which is characteristic of elements in the lanthanide series.

• The 5d^10 indicates that the 5d subshell is fully filled with 10 electrons, a common feature among transition metals.

• The 6s^2 indicates that there are 2 electrons in the 6s subshell, and

• The final part, 6p^1, shows that there is 1 electron in the 6p subshell.

Thallium, which is in group 13 of the periodic table, has a total of 81 electrons. This matches the total count of electrons represented by the
