Answer:
Holmium
Explanation:
Electronic configuration:
[Xe] 6s² 4f⁵ 5d⁶
To know this element, we must first find the atomic number and then look for its position on the periodic table.
Number of electrons in [Xe] = 54;
So the total number of electrons = 54 + 2 + 5 + 6 = 67
This element has an atomic number of 57. On the periodic table, it is Holmium
