What are the physical and chemical properties of boron family?

It is a hard and black coloured non-metallic solid. The existence of boron can be seen in its many allotropic forms. It has an unusually high melting point because of the very strong crystal lattice. In contrast, the rest of the members are soft in nature and have low melting points.

What are the anomalous properties of boron?

Anomalous Properties of Boron

Boron being small is harder than the other elements of its group.
It has higher melting and boiling point than those of the other members of its group.
Boron forms only covalent compounds while all other members form both ionic and covalent compounds.

What are uses of boron?

Amorphous boron is used as a rocket fuel igniter and in pyrotechnic flares. It gives the flares a distinctive green colour. The most important compounds of boron are boric (or boracic) acid, borax (sodium borate) and boric oxide. These can be found in eye drops, mild antiseptics, washing powders and tile glazes.

What is a physical property of boron?

Appearance: Crystalline boron is hard, brittle, lustrous black semimetal. Amorphous boron is a brown powder. Boiling point: 4000 °C. Melting point: 2075 °C. Atomic radius (pm): 98.

What are the physical and chemical properties of Group 13?

Physical Properties of Group 13 Elements

Indium has a lesser nuclear radius than Thallium.
As we move down the group, +1 oxidation state turns out to be steadier than +3 states.
Boron has a high melting point.
All the elements of this family blaze in oxygen at high temperatures framing M2O3.
Aluminium is amphoteric.

What makes up the boron family of elements?

Boron group elements incorporate any of the six chemical elements forming Group 13 (IIIa) of the periodic table. The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and element 113 (briefly named ununtrium [Uut]).

Which is the Trademark Property of the boron family?

The trademark property of the group is that every one of the elements has three electrons in the peripheral shell of their nuclear structure. Boron, the lightest of these elements, is non-metal, yet alternate individuals from the group are brilliant white metals.

What are the chemical properties of group 13 boron?

The elements of group 13 react with halogens at high temperature forming trihalides, MX3. Due to small size and high ionization enthalpy ,boron forms covalent trihalides. BF3 is a gas, BCl3 and BBr3 are liquids while BI3 is a solid. All these trihalide are planar molecules in which Boron is sp2 hybridised.

What is the maximum covalence of the boron family?

Except for boron, the compounds of the elements of the boron family like tetrahedral [M (OH) 4] – and octahedral [M (H 2 O) 6] 3+ (where M denotes the member of boron family) exists in an aqueous medium. The maximum covalence of boron is 4 due to the absence of d orbitals.
