Question

What name is given to the series of ten elements in which the electrons are filling the \(3 d\) sublevel?

Short answer

The name given to the series of ten elements in which the electrons are filling the \(3d\) sublevel is the "First Transition Series." These elements are also known as 3d transition metals.

Step-by-step solution

Identify the 3d sublevel in the periodic table

In the periodic table, elements are organized based on their electron configuration. The 3d sublevel is located in the transition metals section. The series of ten elements filling the 3d sublevel starts from Scandium (Sc, atomic number 21) and ends with Zinc (Zn, atomic number 30).

Name the series of these ten elements

The series of elements in which the electrons are filling the 3d sublevel is called the "First Transition Series." These elements are also known as 3d transition metals.
