Discovery of Black Nitrogen Resolves A Longstanding Chemical Anomaly
Scientists have succeeded in take a crap what they call “ black nitrogen ” anallotrope(form ) expected to exist based on observation of comparable elements , but which had stubbornly eluded them for decades . Theperiodic tablewas essential to chemistry becoming a true skill , based on grouping elements that acquit in a similar manner into columns so that their behavior could be predicted . It was a long time before we discovered the cause for these similarities – that electron ambit in “ cuticle ” and each chemical element in a column has an outermost shell with the same number of electrons , with each words represent an extra shell ....
