What are the examples of transition metals?

Some of the more well-known transitional metals include titanium, iron, manganese, nickel, copper, cobalt, silver, mercury and gold. Three of the most noteworthy elements are iron, cobalt and nickel as they are only elements known to produce a magnetic field.

Where are the transition elements?

Transition elements are the elements that are found in Groups 3-12 (old groups IIA-IIB) on the periodic table (salmon-colored block in the middle of the table).

What are the first transition series elements?

The first main transition series begins with either scandium (symbol Sc, atomic number 21) or titanium (symbol Ti, atomic number 22) and ends with zinc (symbol Zn, atomic number 30). The second series includes the elements yttrium (symbol Y, atomic number 39) to cadmium (symbol Cd, atomic number 48).

What are two transition metals?

The Transition Metals are:

  • Scandium.
  • Titanium.
  • Vanadium.
  • Chromium.
  • Manganese.
  • Iron.
  • Cobalt.
  • Nickel.

What are inner transition elements why they are so called?

The electron obtained on successive filling of 5f orbitals are called actinides or actinides. They are so called because they come immediately after actinium (Ac) in the periodic table. Fourteen elements from Th(90) to Lw(103) comprise actinide series, and are also called second inner transition series.

What is the difference between the transition metals and the inner transition metals?

The main difference between transition metals and inner transition metals is that transition metal atoms have their valence electrons in the outermost d orbital whereas inner transition metal atoms have their valence electrons in the f orbital of the inner penultimate electron shell.

How many inner transition metals are there?

28 inner transition elements
