Transition metals: Returning to the main body of the table, the remainder of Groups 3 through 12 represent the rest of the transition metals. US: Oxford University Press. The vast majority of the known elements are metals. Guide to the Elements Revised ed. It consists of the elements boron Baluminium Algallium Gaindium Inthallium Tland ununtrium Uut unconfirmed. Both systems agree on the numbers. There are 18 numbered groups in the periodic table; the f-block columns between groups 3 and 4 are not numbered.

Originally Answered: What is the group 3 element in the periodic table? The four group 3 elements are. Group 3 is a group of elements in the periodic table. This group, like other d-block groups, should contain four elements, but it is not agreed what elements.
In chemistry, a group is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the f-block columns (between groups 3 and 4).
The element is known to damage cell membranes of water animals, causing several negative influences on reproduction and on the functions of the nervous system.
Actinium, which occurs only in trace amountscontinues the trend in chemical behavior for metals that form tripositive ions with a noble gas configuration; synthetic lawrencium is calculated and partially shown to be more similar to lutetium and yttrium.

|Compounds that contain the fluoride ion are added to toothpaste and the water supply to prevent dental cavities.
Their chemical reactions typically occur more slowly and produce less heat compared to the alkali metals.

Bibcode : JPCS Retrieved 28 April Alkali Metal. The chemical symbols identify the element names. However, it is essential for the methanotrophic bacterium Methylacidiphilum fumariolicum SolV, although the general similarity of the rare earths means that it may be substituted by some of the other early lanthanides with no ill effects.
The Boron group is the series of elements in group 13 (formerly group III) in the periodic table. It consists of the. I think the most mysterious,beautiful and useful elements in our world is Group 3,4,5,6 and 7 know it is time to meet you up with Group 3 elements.

However, lutetium suits the previous elements better in several other properties, such as melting  and boiling points.

Due to the lanthanide contractionlutetium, the last in the lanthanide series, has a significantly smaller atomic radius and a higher nucleus charge,  thus making the extraction of the electrons from the atom to form metallic bonding more difficult, and thus making the metal harder.
Previous Periodic table. Noble Gas. Post-transition metals: Ahead of the jump into the nonmetal world, shared characteristics aren't neatly divided along vertical group lines. It existents elementally in the air as a diatomic molecule, is part of water and a great many minerals, and is essential for life.

These elements, classified as "transition metals“, can be found in group 3 through to 12 of.
Answer metal. Metalloids can have some properties partially like metals and partially like non-metals.
The noble gases are helium, neon, argon, krypton, xenon, and radon. Though selenium is lumped with the non-metals, and can form selenides similar to oxides and sulfides, its elemental state is that of a metalloid semiconductor as is tellurium and polonium. Life depends on carbon.
