Bari mu magana game da yadda za a sami da protons, neutrons da electrons

Bari mu magana game da yadda za a sami da protons, neutrons da electrons. A zarra akwai iri uku na farko barbashi, kuma kowane na da na farko cajin, salla.

A tsarin da tsakiya

Domin fahimtar yadda za a sami da protons, neutrons da electrons, wakiltar musamman core tsarin. Shi ne wani muhimmin bangare ne na zarra. Ciki da tsakiya ne shirya protons da neutrons, kira nucleons. Ciki da tsakiya, wadannan barbashi iya wuce juna.

Alal misali, zan samu protons, neutrons da electrons a hydrogen zarra wajibi ne a san ta jerin lambar. Idan muka yi la'akari da cewa wannan kashi ne karkashin jagorancin lokaci-lokaci tsarin, a tsakiya dauke daya proton.

A diamita wani atomic tsakiya ne goma-dubbai na jimlar zarra size. Yana mayar da hankali da girma daga cikin zarra. By nauyi na core ne mafi girma daga dubu sau Naira Miliyan Xari da duk electrons ba a cikin zarra.

barbashi faye hali

Ka yi la'akari da yadda za a sami da protons, neutrons da electrons a zarra, da kuma koyi game da fasali. Proton - shi ne wani na farko barbashi, wanda yayi dace da tsakiya na hydrogen zarra. Its taro ya wuce electron ne 1836 sau. Don sanin ko naúrar na wutar lantarki ta hanyar wucewa da shugaba tare da wani qaddara giciye-kashi, ta amfani da wani lantarki cajin.

Kowane zarra na wani yawan protons a cikin nucleus din is located. Yana da wani m darajar, halin da sinadaran da jiki Properties na wannan kashi.

Yadda za a sami da protons, neutrons da electrons a carbon zarra? A jerin yawan sinadaran kashi 6, sakamakon haka, shida protons dauke a cikin nucleus din. A cewar planetary model na atomic tsarin, a kusa da wani core motsi a cikin falakinsu shida electrons. Don sanin yawan neutrons daga darajar zumunta atomic taro na carbon (12) debewa da yawan protons (6), mun samu shida neutrons.

da yawan protons m zuwa 26, da cewa shi ne, wannan kashi ne da 26th lamba a cikin lokaci-lokaci tebur zuwa ƙarfe zarra.

A neutron ne electrically tsaka tsaki barbashi, m da free jihar. A neutron ne iya spontaneously canza zuwa wani lallai cajin proton, emitting wani electron da wani antineutrino wannan. A talakawan rabin-rai na 12 minti. Mass lambar - ne total darajar da yawan protons da neutrons a tsakiya na zarra. Bari mu yi kokarin gane yadda za a sami da protons, neutrons da electrons a ion? Idan zarra a lokacin da sinadaran hulda da wani kashi yakan mallaki wani m hadawan abu da iskar shaka jihar, da yawan protons da neutrons cikinta ba canza, kawai electrons zama karami.

Akwai da dama theories bisa tsarin da zarra, amma ba daya daga cikinsu ya ba mai yiwuwa. Kafin version halitta Rutherford, babu cikakken bayani game da wuri a cikin nucleus din protons da neutrons, kazalika da juyawa daga cikin madauwari falakinsu da electrons. Bayan bayyanar da planetary tsarin da zarra ka'idar, da masu bincike da wata dama ba kawai domin sanin yawan na farko barbashi a cikin zarra, amma kuma ya hango ko hasashen da jiki da kuma sinadaran Properties na wani musamman sinadari.
