carbon group

The boiling points of the carbon group tend to get lower with the heavier elements.

The densities of the carbon group elements tend to increase with increasing atomic number.

Lead is classified as a post-transition metal and is also a member of the carbon group.

This compound is aromatic just as the other carbon group representatives silabenzene and stannabenzene.

Folate is needed to carry one carbon groups for methylation and nucleic acid synthesis.

In contrast to porphyrins, corrins lack one of the carbon groups that link the pyrrole-like units.

The suffix -yl used in organic chemistry to form names of carbon groups, was extracted from the word "methyl".

These form when carbon group hydrides react or when heavier versions of carbenes react.

It is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon.

Such compounds typically form from a reaction of carbon group halides and chalcogenol salts or chalcogenol bases.

Chalcogens form single bonds and double bonds with other carbon group elements than carbon, such as silicon, germanium, and tin.

The Group 14 elements, also known as the carbon group and the Group IV elements, is a group of elements on the periodic table.

In known eight-membered clusters of in the same carbon group, tin SnR and germanium GeR the cluster atoms are located on the corners of a cube.

These are in the form of REMPn, where M is a carbon group or boron group element and Pn is any pnictogen except nitrogen.

Contained within this array of transition metal atoms is a second network of main group atoms, typically from group 13 (boron group) or group 14 (carbon group).

Methylation is distinct from alkylation in that it is specifically the transfer of one carbon, whereas alkylation can refer to the transfer of long chain carbon groups.

Sometimes the group number is used, as in group 14 element, and sometimes the name of the first element in the group is used, as in carbon group or carbon family.

Cyclic compounds with chalcogens, carbon group elements, and boron atoms exist, and occur from the reaction of boron dichalcogenates and carbon group metal halides.

At least two of the carbon group elements (tin and lead) have magic nuclei, meaning that these elements are more common and more stable than elements that do not have a magic nucleus.

The other elements may behave differently from what would be predicted by extrapolation, due to relativistic effects; for example, flerovium has been predicted to possibly exhibit some noble-gas-like properties, even though it is currently placed in the carbon group.

The most commonly proposed basis for an alternative biochemical system is the silicon atom, because silicon has many chemical properties similar to those of carbon and is in the same group of the periodic table, the carbon group.

The highest known oxidation state is +8 in the tetroxides of ruthenium, xenon, osmium, iridium, and hassium, and some complexes involving plutonium, while the lowest known oxidation state is 4 for some elements in the carbon group.

He notes that hydrogen shares properties with group 1 elements based on valency, with group 17 elements because hydrogen is a non-metal but also with the carbon group based on similarities in chemical bonding to transition metals and a similar electronegativity.

A simple explanation of the term would state that electropositive atoms (such as carbon groups) attached in close proximity to the potential proton acceptor have an "electron-releasing" effect, such that the positive charge acquired by the proton acceptor is distributed over other adjacent atoms in the chain.
