what group are transition metals?

Many scientists describe a "transition metal" as any element in the d-block of the periodic table, which includes groups 3 to 12 on the periodic table. In actual practice, the f-block lanthanide and actinide series are also considered transition metals and are called "inner transition metals".

Group 1 elements are hydrogen (usually with an asterisk because it also has properties of group 17), lithium, sodium, potassium, rubidium, cesium, and francium—also known as the alkali metals. Group 7 elements are manganese, technetium, rhenium, and bohrium—part of what is known as the transition metals.

Transition elements are those elements that have unpaired electrons or incomplete d orbitals in its ground state or in any OXIDATION STATE. Silver occur in +2 where 1 electron is removed from d orbital resulting in 4d^9 i.e unpaired electron. ... That's why silver is considered as transition metal...

The elements in groups 1B through 8B (also known as 3 through 12) are called the transition metals. Sometimes this block of elements are referred to as the d block. They are called d block elements because the electrons being added in this block of elements are being added to the d orbitals.

The transition metals were given their name because they had a place between Group 2A (now Group 2) and Group 3A (now Group 13) in the main group elements. Therefore, in order to get from calcium to gallium in the Periodic Table, you had to transition your way through the first row of the d block (Sc → Zn).

Many transition metals e.g. iron and platinum are used as catalysts. Many transition metal compounds also show catalytic activity.

Transition metals are essentially metallic elements. ... On the other hand, metalloids are not metal or nonmetals. However, they have chemical and physical properties that lie between metals and nonmetals.

Some properties of transition metals set them apart from other metals. Compared with the alkali metals in group 1 and the alkaline Earth metals in group 2, the transition metals are much less reactive. They don't react quickly with water or oxygen, which explains why they resist corrosion.

Transition Metal. an element that forms one or more stable ions with a partially filled d sub-shell. D Block Element. an element where the D sub-shell is the highest energy sub-shell that is occupied. Ligand.

Post-transition metal. In chemistry, are the metallic elements in the periodic table located between the transition metals to their left and the metalloids to their right. Usually included in this category are Gallium, Indium,Thallium, Tin, Lead and Bismuth.

The transition elements are metals that have a partially filled d subshell (CRC Handbook of Chemistry and Physics) and comprise groups 3 through 12 and the lanthanides and actinides (see below). Post-transition metals. The post-transition elements are Al, Ga, In, Tl, Sn, Pb and Bi.

The IUPAC definition defines a transition metal as "an element whose atom has a partially filled d sub-shell, or which can give rise to cations with an incomplete d sub-shell". ... In actual practice, the f-block lanthanide and actinide series are also considered transition metals and are called "inner transition metals".

Copper is definitely a transition metal because the Cu2+ ion has an incomplete d level. Here you are faced with one of the most irritating facts in chemistry at this level! ... However, in all the chemistry of the transition elements, the 4s orbital behaves as the outermost, highest energy orbital.

A transition metal is one that forms one or more stable ions which have incompletely filled d orbitals. On the basis of this definition, scandium and zinc do not count as transition metals - even though they are members of the d block.

There are four main groups of elements in the periodic table: main group metals, non-metals, metalloids, and transition metals (See types of elements).

Many chemistry textbooks and printed periodic tables classify La and Ac as group 3 elements and transition metals, since their atomic ground-state configurations are s2d1 like Sc and Y. The elements Ce–Lu are considered as the "lanthanide" series (or "lanthanoid" according to IUPAC) and Th–Lr as the "actinide" series.
