Which element corresponds to the configuration [Xe] 6s^2 4f^14 5d^10 6p^2?

The electron configuration given is [Xe] 6s² 4f¹⁴ 5d¹⁰ 6p². To determine which element this corresponds to, we need to break down the notation.

The part of the configuration [Xe] indicates that the first 54 electrons are represented by the electron configuration of Xenon, which is a noble gas. Following this, the configuration adds electrons in the following orbitals: 6s, 4f, 5d, and finally the 6p orbital.

Adding the electrons in each section:

• 6s contributes 2 electrons.

• 4f contributes 14 electrons.

• 5d contributes 10 electrons.

• 6p contributes 2 electrons.

When you sum these values: 2 (from 6s) + 14 (from 4f) + 10 (from 5d) + 2 (from 6p) equals 28. Therefore, including the 54 from Xenon gives a total of 54 + 28 = 82 electrons.

The atomic number corresponds to the number of electrons in a neutral atom, and an atomic number of 82 identifies the element Lead (Pb). The electron
