    The use 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. Borax used to be used to make bleach and as a food . The isotope boron-10 is good at absorbing neutrons. This means it can be used to regulate nuclear reactors. It also has a role in instruments used to detect neutrons. Boron is essential for the cell walls of plants.

    The use of Aluminum - Aluminium is used in a huge variety of products including cans, foils, kitchen utensils, window frames, beer kegs and aeroplane parts. This is because of its particular properties. Aluminium is a good electrical conductor and is often used in electrical transmission lines. It is cheaper than copper and weight for weight is almost twice as good a conductor.

    An isolated atom is an atom with the same number of electron as protons yeilding a net charge of 0. The properties of an atom in isolation is different from that of individual atoms in relatively close proximity to each other.Thus, atoms are almost always found associated in some way with other atoms.

    Interaction between gas molecule is very weak or very very less therefore to study them we take a single atom of a gas which depicts overall property of a gas. since the molecules are not lose in the gas that is interaction is weak therefore it is said to be an isolated gaseous atom. Isolated means it is not bonded with strong bonds like ionic or covalent.

    alkane , any of a group of aliphatic hydrocarbons whose molecules contain only single bonds (see chemical bond ). Alkanes have the general chemical formula C n H 2n+2 . An alkane is said to have a continuous chain if each carbon atom in its molecule is joined to at most two other carbon atoms; it is said to have a branched chain if any of its carbon atoms is joined to more than two other carbon atoms. The first four continuous-chain alkanes are methane , CH 4 ; ethane , C 2 H 6 ; propane , C 3 H 8 ; and butane , C 4 H 10 . Names of continuous-chain alkanes whose molecules contain more than five carbon atoms are formed from a root that indicates the number of carbon atoms and the suffix - ane to indicate that the compound is an alkane; e.g., alkanes with 5, 6, 7, 8, 9, and 10 carbon atoms in their molecules are pentane, hexane, heptane, octane, nonane, and decane, respectively. The name of a branched-chain alkane is formed by adding prefixes to the name of the continuous-chain alkane from which it is considered to be derived; e.g., 2-methylpropane (called also isobutane) is thought of as being derived by replacing one of the hydrogen atoms bonded to the second (2-) carbon atom of a propane molecule with a methyl (CH 3 ) group, forming CH 3 CH(CH 3 ) 2 . Chemically, the alkanes are relatively unreactive.

    The delocalization of σ-electrons or lone pair of electrons into adjacent π-orbital or p-orbital is called hyperconjugation. It occurs due to overlapping of σ-bonding orbital or the orbital containing a lone pair with adjacent π-orbital or p-orbital. It is also known as "no bond resonance" or "Baker-Nathan effect". No bond also known as hypetconjugation

    Alkynes can also be hydrogenated with sodium in liquid ammonia at low temperatures. This reaction is a chemical reduction rather than a catalytic reaction, so the hydrogen atoms are not attached to a surface, and they may approach an alkene from different directions, leading to the formation of trans alkenes.

    2Thank You

    Ankit Singh 7 years ago

    Lindlar catalyst (palladium on Ba S O 4 , poisoned with quinoline) is frequently used for this hydrogenation which stereospecifically yields cis products. Reduction of alkynes with sodium in liquid ammonia (solvated electrons) yields trans alkenes.

    The force acting per unit length perpendicular to the tangential line drawn on the surface of liquid is called surface tension .

    1Thank You

    Ayushi Ayushi 7 years ago

    Surface Tension Definition. Surface tension is a physical property equal to the amount of force per unit area necessary to expand the surface of a liquid. ... Surface tension forces are due to intermolecular forces between the liquid's molecules at the liquid's outer boundaries.
