Main-group element In chemistry and atomic physics, the main group is the group of elements whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon as arranged in the periodic table of the elements.

Periodic table The rows of the table are called periods; the columns are called groups. Six groups (columns) have names as well as numbers: for example, group 17 elements are the halogens; and group 18, the noble gases.The periodic table can be used to derive relationships between the properties of the elements, and predict the properties of new elements yet to be discovered or synthesized.he number of possible elements is not known. A very early suggestion made by Elliot Adams in 1911, and based on the arrangement of elements in each horizontal periodic table row, was that elements of atomic weight greater than 256± (which would equate to between elements 99 and 100 in modern-day terms) did not exist.

Elements as Building Blocks Now you know about periods going left to right. The periodic table also has a special name for its vertical columns. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its outer shell.

10 Periodic Table Facts The rows of the periodic table are called periods. An element's period number is the highest unexcited energy level for an electron of that element. Columns of elements help to distinguish groups in the periodic table.

Elements for Kids Boron is the first element in the thirteenth column of the periodic table. It is classified as a metalloid which means that its properties are in between that of a metal and a nonmetal.

Group 5 element Group 4 is a group of elements in the periodic table. It contains the elements titanium (Ti), zirconium (Zr), hafnium (Hf) and rutherfordium (Rf). This group lies in the d-block of the periodic table. The group itself has not acquired a trivial name; it belongs to the broader grouping of the transition metals.

Carbon family The carbon family consists of the five elements that make up Group 14 of the periodic table: carbon, silicon, germanium, tin, and lead. The family is particularly interesting because it consists of one nonmetal (carbon), two metals (tin and lead), and two metalloids (silicon and germanium).

The Periodic Table Atomic number describes the number of protons in one atom of that element. For example, an atom of oxygen contains 8 protons. Elements are listed in order of increasing atomic number from left to right. Each row of the periodic table is called a period and each column of the periodic table is called a group (or family).

Group 11 element Group 11, by modern IUPAC numbering, is a group of chemical elements in the periodic table, consisting of copper (Cu), silver (Ag), and gold (Au).

Main-group element In chemistry and atomic physics, the main group is the group of elements whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements. The main group includes the elements (except hydrogen, which is sometimes not included) in groups 1 and 2 , and groups 13 to 18 .

- In the periodic table of elements, there are seven horizontal rows of elements called periods. The vertical columns of elements are called groups, or families. (See also The Periodic Table: Metals, Nonmetals, and Metalloids.) In each period (horizontal row), the atomic numbers increase from left to right.

- Position of Transition Metals in the Periodic Table. The elements in the periodic table are often divided into four categories: (1) main group elements, (2) transition metals, (3) lanthanides, and (4) actinides. The main group elements include the active metals in the two columns on the extreme left of the periodic table and the metals, semimetals, and nonmetals in the six columns on the far right. The transition metals are the metallic elements that serve as a bridge, or transition, between the two sides of the table.

Group (periodic table) In the old IUPAC system the letters A and B were designated to the left (A) and right (B) part of the table, while in the CAS system the letters A and B are designated to main group elements (A) and transition elements (B).

What Is the Purpose of the Periodic Table? Credit: David B. Gleason CC-BY-2.0. Elements are placed on the periodic table based on their atomic structure. Each row and column has specific characteristics. All the rows on the table are read left to right and each row is called a period. Each column on the table is called a group. Each group has the same number of electrons.

- Periodic means repeats at regular intervals.In the periodic table, elements are arranged in vertical columns. These columns are called groups or families. The groups are as follows: Group:IA: (except for H): alkali metals. The most reactive of all metals Group: IIA: the alkaline earth metals.

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). In modern IUPAC notation, it is called Group 14. In the field of semiconductor physics, it is still universally called Group IV.

Main-group element The periodic table of the chemical elements. The columns represent the groups. Groups 1, 2 and 13 to 18 constitute the main group. Sometimes groups 3 and 12, as well as the lanthanides and actinides (the two rows at the bottom), are also included in the main group.

Periodic Table and Trends Review The horizontal rows on the periodic table are called periods. Most of the elements in the periodic table are classified as metals. The elements that touch the zigzag line are classified as metalloids. The elements in the far upper right corner are classified as nonmetals. Elements in the first group have one outer shell electron and are extremely reactive. They are called alkali metals. Elements in the second group have 2 outer shell electrons and are also very reactive. They are called earth alkali metals. Elements in groups 3 through 12 have many useful properties and are called transition metals. Elements in group 17 are known as “salt formers”. They are called halogens.

General Chemistry/Print version A vertical column in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell. Period. A horizontal row in the periodic table. The atomic number of each element increases by one, reading from left to right. Block. Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). Atomic number. The number of protons in an atom.

- The alkali metals, halogens and noble gases are three important groups in the periodic table. The alkali metals are soft, reactive metals. They react vigorously with water and become more reactive as you go down the group.
