Igolide yintsimbi exabisekileyo. Abantu abaninzi bayithenga ngenjongo yokugcina nokuxabisa ixabiso layo. Kodwa into ephazamisayo kukuba abanye abantu bafumana izitena zegolide okanye iingqekembe zegolide zesikhumbuzo zigqwalile.
Igolide ecocekileyo ayizukugqwala
Uninzi lweentsimbi lusabela kwi-oksijini ukuze lwenze ii-oxide zesinyithi, esizibiza ngokuba yi-rust. Kodwa njengesinyithi esixabisekileyo, igolide ayigqwali. Kutheni? Lo ngumbuzo onomdla. Kufuneka sisombulule imfihlakalo evela kwiimpawu zegolide.
Kwikhemistri, i-oxidation reaction yinkqubo yekhemikhali apho into ethile ilahlekelwa zii-electron ize ibe zii-ions ezintle. Ngenxa yomxholo ophezulu we-oxygen kwindalo, kulula ukufumana ii-electron kwezinye izinto ukuze zenze ii-oxides. Ke ngoko, le nkqubo siyibiza ngokuba yi-oxidation reaction. Amandla e-oxygen okufumana ii-electron aqinisekile, kodwa amathuba okuba into nganye ilahlekelwe zii-electron ahlukile, nto leyo exhomekeke kumandla e-ionization ee-electron zangaphandle zento.
Ulwakhiwo lwe-athomu yegolide
Igolide inokumelana okunamandla kwe-oxidation. Njengesinyithi esiguqukayo, amandla ayo okuqala e-ionization afikelela kwi-890.1kj/mol, ilandela i-mercury (1007.1kj/mol) ngasekunene kwayo. Oku kuthetha ukuba kunzima kakhulu ukuba ioksijini ibambe i-electron kwigolide. Igolide ayinayo nje kuphela amandla aphezulu e-ionization kunezinye iimetali, kodwa ikwanayo ne-atomization enthalpy ephezulu ngenxa yee-electron ezingadibaniyo kwi-6S orbit yayo. I-atomization enthalpy yegolide yi-368kj/mol (i-mercury yi-64kj/mol kuphela), oko kuthetha ukuba igolide inamandla amakhulu okubopha isinyithi, kwaye ii-athomu zegolide zitsaleleka kakhulu kwenye, ngelixa ii-athomu ze-mercury zingatsalelekanga kakhulu kwenye, ngoko ke kulula ukugrunjwa zezinye ii-athomu.
