Transition elements have high polarizing power due to their small atomic and ionic sizes, which leads to a high charge density on the nucleus. This high charge density results in a stronger attraction to the electrons in neighboring atoms, causing distortion in their electron cloud. This ability to distort the electron cloud of neighboring atoms is what gives transition elements high polarizing power.

Do the transition elements display metallic or non metallic properties?
Transition elements display metallic properties, such as high electrical and thermal conductivity, malleability, and ductility. However, some transition elements can also exhibit nonmetallic properties depending on their oxidation states and bonding characteristics.
What does the term polarising power of a cation mean?
Polarizing power: Polarising power is the ability of an atom or group of atoms to attract the shared pair of electrons toward itself. For example: If you have aluminium chloride.... the aluminium ion has a 3+ charge and is relatively small. The chlorine ion has a 1- charge and is larger than the aluminium ion. As a result...the aluminium ion has a higher charge density (i.e. a stronger attraction) and so attracts the shared pair of electrons (between the chlorine and aluminium) towards itself. we say aluminium has high polarising power because of its ability to do this. And the chlorine is easily polarised because the electrons get taken away from it.
What is the group 3b-12b elements know as?
The group 3b-12b elements are known as the transition metals. They are characterized by their ability to form colorful compounds, exhibit variable oxidation states, and have high melting and boiling points. Many transition metals are used in industrial applications and play important roles in biological systems.
Group 3-12 contain metals known as?
Group 3-12 contains transition metals, which are elements that have partially filled d or f electron shells. These metals have characteristic properties such as high melting points, ductility, and the ability to form colored compounds. Some commonly known transition metals in this group include iron, copper, and zinc.
Which group occupies the large middle section of the periodic table?

Do the transition elements display metallic or non metallic properties?
Transition elements display metallic properties, such as high electrical and thermal conductivity, malleability, and ductility. However, some transition elements can also exhibit nonmetallic properties depending on their oxidation states and bonding characteristics.
What are the Group B elements?
Group B elements are the transition metals in the periodic table, also known as the d-block elements. They include elements from scandium (Sc) to zinc (Zn) and have properties such as high melting and boiling points, variable oxidation states, and the ability to form colored compounds. These elements are important in various industrial processes and applications.
How would you describe the elements in groups 3-12?
Transition Metals; The general properties of the transition elements areThey are usually high melting point metals.They have several oxidation states.They usually form colored compounds.They are often paramagnetic.

What is the name of groups 3-12 name on the periodic table?
The groups from 3 to 12 are called transitional metals because the last two shells of the elements included in these groups are incompletely filled. They are also included in d-block.Groups 3 through 12 are called the transition metals or the d-block.
Which set of properties is most characterictic of transition elements?
Colored ions in solution, multiple positive oxidation states.
What family element does mercury belong to?
Mercury belongs to the family of elements called transition metals. These elements are known for their variability in oxidation states and ability to form complex compounds. Mercury is specifically classified as one of the heavy transition metals due to its high density.
Why transition metal is also called heavy metal?
Transition metals are often referred to as "heavy metals" due to their high density compared to other elements. They have large atomic masses and many of them are toxic. However, it is important to note that the term "heavy metal" is also used to describe a group of elements with specific properties related to their electronic structure, not just their weight.
Why transitional elements have high enthalpy of atomisation?
Transition elements have high enthalpy of atomization because of their relatively large number of electrons and complex electron configurations. These elements have multiple unpaired electrons in their d orbitals, leading to strong metallic bonding and high stability in the solid state. As a result, it requires more energy to break the strong metallic bonds and separate the atoms, resulting in a high enthalpy of atomization.
