Lesson Transcript
Instructor: Elizabeth (Nikki) Wyman

Nikki has a master's degree in teaching chemistry and has taught high school chemistry, biology and astronomy.

The heart of the periodic table is home to some of the most famous metals, the transition metals. Learn the definition of a transition metal, look at a list of them, and learn some of their properties. Then, assess your knowledge with a quiz.

Definition of Transition Metals

Elements that lose electrons easily, that are lustrous and malleable, and that are good conductors of heat and electricity are known as metals. Metal elements can be broken down into several categories, one of which is the category of transition metals.

A transition metal is defined as a metal with inner d or f orbitals being filled. Orbitals describe ways that electrons can be organized around a nucleus. There are four types of orbitals: s, p, d, and f.

The transition metals consist of the 40 elements located in columns 3-12 on the periodic table and the 28 elements comprising the lanthanide and actinide series. Elements in the lanthanide and actinide series are often considered to be inner transition metals. The transition metals are identifiable in the periodic table shown here in peach; the inner transition metals are dark pink and light pink in color. The d-block transition metals are in columns 3-12, often labeled 1B-10B in other versions of the periodic table. The f-block inner transition metals are in the two long rows below the periodic table. Inner transition metals are often just referred to as transition metals.

There are nearly 100 transition metals, so it would take a little too long to list them all in this video. However, it might be useful to you to remember that transition metals include:

  • Scandium (21) through zinc (30)
  • Yttrium (39) through cadmium (48)
  • Lanthanum (57) through mercury (80)
  • Actinium (89) through copernicium (112)

Properties of Transition Metals

Transition metals show similar properties by column and by row. In general, transition metals are lustrous, silvery, hard, and good conductors of heat and electricity. Properties between individual elements may vary greatly. For instance, mercury is a liquid at room temperature, whereas tungsten does not melt until 3,400 degrees Celsius.

Mercury, often known as quicksilver, is a liquid at room temperature. It is one of the oldest metals known to humans.

Some elements are extremely malleable, like gold and silver, while others, like cobalt, are more difficult to mold. Some metals, like copper, are very ductile and can be made into wires. Nearly all of the metals are good conductors of heat and electricity, but some are better than others. Copper and silver are amongst the best conductors.

Unlike elements from the rest of the periodic table, transition metals are comfortable losing different numbers of electrons. Whereas elements from column one can only ever form charges of +1, a single transition metal may be able to form variously charged ions. Iron, for example, can exist with a +2 or +3 charge.

Vanadium can exist with a charge between +2 and +5. The ability to have multiple types of cations is related to the organization of electrons in the d and f orbitals.

Chemical reactivity of the transition metals varies greatly. Some metals will react to form compounds, while others prefer to remain in their pure form. Many transition metals, like iron and titanium, will readily react with oxygen to form oxides. Other transition metals, like gold and platinum, are less reactive and can lie for thousands of years next to oxygen without reacting.

Famously unreactive gold is often found in its pure form.
