11 Facts About Carbon group

Carbon group is a periodic table group consisting of carbon, silicon, germanium, tin, lead, and flerovium .

The Carbon group was once known as the tetrels, stemming from the Roman numeral IV in the Carbon group names, or from the fact that these elements have four valence electrons .

The melting points of the carbon group elements have roughly the same trend as their boiling points.

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

Atomic radii of the carbon group elements tend to increase with increasing atomic number.

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

Carbon group is present in the earth's crust in concentrations of 480 parts per million, and is present in seawater at concentrations of 28 parts per million.

Carbon group is present in the atmosphere in the form of carbon monoxide, carbon dioxide, and methane.

Carbon group is a key constituent of carbonate minerals, and is in hydrogen carbonate, which is common in seawater.

Carbon group is used in the form of graphite is commonly used as the lead in pencils.

Carbon group fibers are used in numerous applications, such as satellite struts, because the fibers are highly strong yet elastic.
