Generally, electrons are fed into orbitals in order of increasing energy until all the electrons have been accommodated. The general valence shell electron configuration of the d-block elements is (n-1)d1-10ns1-2. The electrons fill the d subshell of these elements according to the following rules . 1. Electrons fill atomic orbitals according to th...
The partially filled d subshell and the ease at which electrons can be removed from or placed in the d orbitals give rise to several unique chemical properties. These include : 1. Forming colored compounds 2. Behaving as catalyst 3. Multiple oxidation states The 4s electrons are shielded from the atomic nucleus by the 3d electrons. Therefore, the 4...
As in the case of the s-block and p-block elements, the size of neutral atoms of the d-block elements gradually decreases from left to right across a period due to an increase in the effective nuclear charge with increasing atomic number. The atomic radius increases down a group due to increasing atomic number. The increase in size between Period 4...
Due to their unique electron configuration, the d-block elements possess unique physical properties that differ from the s-block and p-block elements. These include : 1. Malleability – the ability to be hammered into flat sheets or drawn into wires 2. Ductility – the ability to pull into thin wires 3. Good conductors of heat and electricity – valan...

Transition metal - Wikipedia. Transition metals in the periodic table. In chemistry, a transition metal (or transition element) is a chemical element in the d-block of the periodic table (groups 3 to 12), though the elements of group 12 (and less often group 3) are sometimes excluded.
The d-block of the periodic table contains the elements of the groups 3-12 in which the d orbitals are progressively filled in each of the four long periods. The f-block consists of elements in which 4 f and 5 f orbitals are progressively filled. They are placed in a separate panel at the bottom of the periodic table.
