are transition metals in group 2?
316383
The name transition metal refers to the position in the periodic table of elements. The transition elements represent the successive addition of electrons to the d atomic orbitals of the atoms. In this way, the transition metals represent the transition between group 2 (2A) elements and group 13 (3A) elements.

The 38 elements in groups 3 through 12 of the periodic table are called "transition metals". As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat.

All the elements in Group 2 have two electrons in their valence shells, giving them an oxidation state of +2. Covers the elements beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr) and barium (Ba).

Transition metals. The transition elements are metals. They have high melting points and densities, and are strong and hard. They form coloured compounds and act as catalysts.

The transition metals are placed in the central part of the periodic table . The transition metals are placed between groups 2 and 3 in the periodic table.

Typically the elements of the post-transition metals include any metal in groups 13, 14, and 15 which are aluminum, gallium, indium, tin, thallium, lead, and bismuth. Polonium is often classified as a post-transition metal as well.

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.

Group 2 elements share common characteristics. Each metal is naturally occurring and quite reactive. These metals are silver and soft, much like the alkali metals of Group 1. These metals also react with water, though not as vigorously.
1414267
All the transition elements are metals; this is because the number of electrons in outermost shell is only 2. Transition metals are hard, malleable and ductile due to presence of strong metallic bonds.

They are manganese (Mn), technetium (Tc), rhenium (Re), and bohrium (Bh). All known elements of group 7 are transition metals.

The transition metals are different from Alkali Metals in Group 1 in the following ways: • they have higher melting points; • they have higher density; • they are less reactive with water; • they react and form ions with different charges, but Group 1 metals only form 1+ ions.

Each of these atoms would readily take on two electrons to have a filled valence shell and become stable as O−2 , and S−2 . Each element having an oxidation state of -2. There are exceptions to the rules and the transition metals usually have more than one oxidation state.

The transition metals have the following chemical properties in common: they are less reactive than alkali metals such as sodium. they form coloured ions of different charges. some are very unreactive (silver and gold)

Transition Metals 9-12. The transition metals make up the middle block of the periodic table (seen below). Like the other elements that are grouped together (alkali metals, halogens), these metals have very similar properties. ... Much of the way an element behaves is a result of the configuration of its outer electrons.
