Final answer:
Transition metals are elements with partially filled d orbitals, located in the d-block of the periodic table. Some transition metals, such as platinum, gold, and silver, are almost inert or nonreactive.
Step-by-step explanation:
Transition metals are elements with partially filled d orbitals, located in the d-block of the periodic table. They exhibit chemical behavior typical of metals, such as oxidizing in air upon heating and reacting with elemental halogens to form halides. However, some transition metals are more inert or nonreactive compared to others.
For example, platinum, gold, and silver are transition metals that are almost inert or nonreactive. They can be found in nature in their free, or uncombined, state due to their low reactivity. These elements are widely used in jewelry and other applications for their durability and resistance to corrosion.
So, out of the families mentioned, the transition metals are not completely inert or nonreactive, but there are some members within the transition metals that can be considered as such.
