electropositive उदाहरण वाक्य

उदाहरण वाक्य
41.The atomic s character on the carbon atom has been directed toward the more electropositive hydrogen substituents and away from the electronegative fluorine, which is exactly what Bent's rule suggests.

42.In contrast to the " valency number ", the " oxidation state " can be positive ( for an electropositive atom ) or negative ( for an electronegative atom ).

43.Oxygen primary ions are often used to investigate electropositive elements due to an increase of the generation probability of positive secondary ions, while caesium primary ions often are used when electronegative elements are being investigated.

44.Niobium is slightly less electropositive and more compact than its predecessor in the periodic table, zirconium, whereas it is virtually identical in size to the heavier tantalum atoms, as a result of the lanthanide contraction.

45.SharkDefense conducted corrosion loss studies in 2008 at South Bimini, Bahamas, and found that a 70 gram piece of a custom electropositive alloy retained more than 50 % of its original weight after 70 hours of immersion.

46.:A metal may be said to differ from a metalloid [ that is, a nonmetal ] in being an excellent conductor of heat and electricity, in reflecting light more or less powerfully and in being electropositive.

47.An electropositive metal, which was a component of a permanent magnet, was chosen as an experimental control for a tonic immobility experiment by Eric Stroud using a juvenile lemon shark ( " Negaprion brevirostris " ).

48.The structure of Na 3 As is complex with unusually short Na Na distances of 328 330 pm which are shorter than in sodium metal, and this indicates that even with these electropositive metals the bonding cannot be straightforwardly ionic.

49.This is done in a Downs cell in which the NaCl is mixed with calcium chloride to lower the melting point below 700 �C . As calcium is less electropositive than sodium, no calcium will be deposited at the cathode.

50.In predicting the bond angle of water, Bent s rule suggests that hybrid orbitals with more s character should be directed towards the very electropositive lone pairs, while that leaves orbitals with more p character directed towards the hydrogens.
