30 Ιουν 2023 · 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 ...

Group 13 elements (Boron Family) are the 1st group of p-block. Elements: Boron, Aluminium, Gallium, Indium, Thallium. Understand their properties, Behaviour and Compounds formed.
Table summarizes the physical properties of the Group 13 elements. While, aluminum, indium, and thallium have typical metal properties, gallium has the largest liquid range of any element. Boron exists as a molecular compound in the solid state, hence its high melting point.
The group 13 elements are prepared by reduction of halides or oxides or, in the case of boron, thermal decomposition of the hydride. Boron can be prepared by reduction of its halides or high temperature thermal decomposition of its hydrides.
Definition. Group 13 elements, also known as the boron group, include boron (B), aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). These elements are characterized by having three valence electrons, which significantly influence their bonding behavior and structural properties in compounds.
Several group 13 elements have biological roles in the ecosystem. Boron is a trace element in humans and is essential for some plants. Lack of boron can lead to stunted plant growth, while an excess can also cause harm by inhibiting growth. Aluminium has neither a biological role nor significant toxicity and is considered safe.
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.
