Periodic table of Mendeleev.

Transition metals are elements located in the middle of the fourth, fifth and sixth periods of the periodic table.

All the atoms of these elements in the unexcited state have valence electrons at the s and d orbitals-sublevels.

Scandium is the first element with an electron ...

... sizes of transition metal atoms decrease.

Electrons in 4 f orbitals compress the electron shell of atoms even more than in 3 d.

Despite the significant differences in the ordinal numbers, the atomic radii d of elements of 5 and 6 periods are close.

Therefore, the properties of these metals in groups are very ...

... Transition metals under normal conditions have either a volume-centered cubic, or a face-centered cubic, or a hexagonal lattice of dense packing.
