Question

use the periodic table to determine the element corresponding to the electron configuration xe6s²4f¹⁴5d⁵
enter the chemical symbol of the element.

Explanation:

Step1: Determine the number of electrons from Xe

Xe (Xenon) has 54 electrons.

Step2: Calculate the total number of electrons

The electron configuration is \([Xe]6s^{2}4f^{14}5d^{9}\). The number of electrons from \(6s^{2}\) is 2, from \(4f^{14}\) is 14, and from \(5d^{9}\) is 9. So the total number of electrons is \(54 + 2+14 + 9=79\).

Step3: Identify the element

The element with 79 electrons (atomic number 79) is gold.
