Answer» #nitrogen occupies about 78% of air #nitrogen is gas at room temperature #nitrogen has an electronic configuration of 1s2 2s2 2p3#it is most unreactive gas due to its half filed electronic configuration this half filled configuration gives some extra stability #nitrogen is also an important gas to all living organism like nitrogen fixation in plants #nitrogen is filled in bulbs due to its inertness of reactivity #generally carbon family forms covalent bonds #it\'s General outer electronic configuration is ns2 np2#in whole periodic table carbon only has the capability to form n number of #compounds so only it is taken as separate big type of chemistry i.e organic chemistry #carbon family is generally tetravalent In nature #these are non metals and some are metaloids like silicon NITROGEN FAMILY --This group is also known as the nitrogen family. It consists of the elements nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi).The top two elements, nitrogen and phosphorus, are very definitely nonmetals, forming -3 charge anions. Nitrogen is a diatomic gas and phosphorus is a solid. The elements arsenic, antimony, and bismuth all have some characteristics of semimetals such as brittleness as a free element.CARBON FAMILY--Group 14 is the carbon family. The five members are carbon, silicon, germanium, tin, and lead. All of these elements have four electrons in their outermost energy level. Of the Group 14 elements, only carbon and silicon form bonds as nonmetals (sharing electrons covalently).Metallic properties increase down the group. Carbon is a non-metal, silicon and germanium are metalloids, and tin and lead are poor metals (they conduct heat and electricity less effectively than other metals such as copper). Despite their adherence to periodic trends, the properties of the carbon family vary greatly. I Hope this will help you.? |
