Aluminium, Gallium, Indium and Thallium - ScienceDirect ~ Gallium is also unusual in contracting on melting, the volume of the liquid phase being 3.4% less than that of the solid; the same phenomenon occurs with the next element in the periodic table Ge, and also with Sb and Bi, in addition to the well-known example of H 2 O. In each case, a structural feature in the solid is broken down to permit more efficient packing of atoms in the liquid state.
Boron Family: Group 13 Elements, Occurence, Properties ~ The group 13 elements consist of six elements. They are boron (B), aluminium (Al), gallium (Ga), Indium (In), thallium (Tl), and element 113. This element gets the name of ununtrium [Uut]. The commonest property of the group is that each one of the elements has three electrons in the outer shell of their nuclear structure. Boron is the lightest .
WebElements Periodic Table » Boron » the essentials ~ Boron is a Group 13 element that has properties which are borderline between metals and non-metals (semimetallic). It is a semiconductor rather than a metallic conductor. Chemically it is closer to silicon than to aluminium, gallium, indium, and thallium. Crystalline boron is inert chemically and is resistant to attack by boiling HF or HCl .
boron group element / Properties & Facts / Britannica ~ Boron group element, any of the six chemical elements constituting Group 13 (IIIa) of the periodic table. The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh). They are characterized by having three valence electrons.

Thallium / chemical element / Britannica ~ Thallium (Tl), chemical element, metal of main Group 13 (IIIa, or boron group) of the periodic table, poisonous and of limited commercial value. Like lead, thallium is a soft, low-melting element of low tensile strength. Freshly cut thallium has a metallic lustre that dulls to bluish gray upon
Group 13: Physical Properties of Group 13 - Chemistry ~ Properties and Periodic Trends. These elements are found in Group 13 (XIII) of the p block in the Periodic Table of Elements. Aluminum, gallium, indium, and thallium are metallic. They each have three electrons in their outermost shell (a full s orbital and one electron in the p orbital) with the valence electron configuration ns 2 np 1. The boron family adopts oxidation states +3 or +1. The .

Group 13 (IIIA) - ChemEd DL ~ Group 13 is sometimes referred to as the boron group, named for the first element in the family. These elements are--not surprisingly--located in column 13 of the periodic table. This group includes boron, aluminum, gallium, indium, thallium, and ununtrium (B, Al, Ga, In, Tl, and Uut, respectively). These elements all have three valence electrons. Boron is the only metalloid in this family .

Group 3 Elements - Periodic Table Trends ~ Group 3 elements have 3 valence electrons. Group 3 elements can react by losing 3 electrons. When the 3 electrons are lost, a full shell of 8 electrons is exposed, creating more stable conditions. Elements which fall into group 3, are said to be part of the boron group. Members of the boron group include:
Boron group - Wikipedia ~ The boron group are the chemical elements in group 13 of the periodic table, comprising boron (B), aluminium (Al), gallium (Ga), indium (In), thallium (Tl), and perhaps also the chemically uncharacterized nihonium (Nh). The elements in the boron group are characterized by having three valence electrons. These elements have also been referred to as the triels.
Thallium - Element information, properties and uses ~ 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).
Thallium - Wikipedia ~ Thallium is a chemical element with the symbol Tl and atomic number 81. It is a gray post-transition metal that is not found free in nature. When isolated, thallium resembles tin, but discolors when exposed to air.Chemists William Crookes and Claude-Auguste Lamy discovered thallium independently in 1861, in residues of sulfuric acid production. . Both used the newly developed method of flame .

Boron, Chemical Element - structure, reaction, water, uses ~ Boron is the first element in Group 13 (IIIA) of the periodic table. The periodic table is a chart that shows how the chemical elements are related to each other. The elements in this group are usually referred to as the aluminum family. Boron is quite different from other members of the family. One difference is that boron is not a metal. All other members of the family (aluminum, gallium .
Periodic Table of the Elements / Sigma-Aldrich ~ The periodic table (also known as the periodic table of elements) is organized so scientists can quickly discern the properties of individual elements such as their mass, electron number, electron configuration and their unique chemical properties.
