  2. Carbon group - Wikipedia

    en.wikipedia.org/wiki/Carbon_group

    The carbon group is a periodic table group consisting of carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). It lies within the p-block. In modern IUPAC notation, it is called group 14. In the field of semiconductor physics, it is still universally called group IV.

    The Roman numerals used correspond to the last digit of today's naming convention (e.g. the group 4 elements were group IVB, and the group 14 elements were group IVA). In Europe, the lettering was similar, except that "A" was used for groups 1 through 7, and "B" was used for groups 11 through 17. In addition, groups 8, 9 and 10 used to be ...

  5. Group (periodic table) - Wikipedia

    en.wikipedia.org/wiki/Group_(periodic_table)

    In the periodic table of the elements, each column is a group. In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.

    The other group 14 elements have a lower tendency to catenate. Hydrosilicons ( binary silicon-hydrogen compounds ), a silicon analogs of hydrocarbons, such as silanes Si n H 2 n +2 are known for n = 1–8, in which thermal stability decreasing as n increases (e.g. silane SiH 4 and disilane Si 2 H 6 ), as are cyclosilanes (e.g. cyclopentasilane ...

    en.wikipedia.org/wiki/Help:Periodic_table...

    Groups (columns in the periodic table; sometimes called 'family') are numbered 1–18, following modern IUPAC guidelines. So called trivial group names, like halogens, are well defined and acceptable. Each group can also be identified by its top element: group 14 = carbon group.

  8. List of chemical elements - Wikipedia

    en.wikipedia.org/wiki/List_of_chemical_elements

    A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...

  9. Silicon - Wikipedia

    en.wikipedia.org/wiki/Silicon

    Silicon is a chemical element; it has symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid and semiconductor . It is a member of group 14 in the periodic table: carbon is above it; and germanium , tin , lead , and flerovium are below it.
