Chromium 54 : Cov tus lej atomic Z = 24, os nyob ntawd yog 24 protons thiab 24 electrons. Cov pawg A = 54 . Tus lej ntawm neutrons = A– Z = 54 – 24 = 30.

Hauv qhov no, pes tsawg neutrons nyob hauv chromium 53 nuclide?

Isotopes zoo sib xws vim lawv muaj tib tus lej protons . Piv txwv li, tag nrho cov isotopes ntawm Chromium muaj 24 protons . Chromuim - 50 muaj pes tsawg leeg ntawm 50 thiab 26 neutrons qhov twg Chromium - 52 muaj ntau tus lej ntawm 52 thiab 28 neutrons thiab Chromium - 53 muaj ib tug loj tus naj npawb ntawm 53 thiab 29 neutrons.

Qhov thib ob, muaj pes tsawg protons nyob rau hauv chromium 52 nuclide? 24 proton

Ib yam li ntawd, nws tau nug, pes tsawg neutrons chromium 50 muaj?

Piv txwv li, chromium - 50 muaj atomicmass 50 , thiab koj paub tias muaj 24 protons inchromium , koj tuaj yeem rho tawm 24 ntawm 50 uas muab rau koj 26. Koj tuaj yeem qhia tau tias koj muaj 26 neutrons.

Dab tsi yog qhov loj ntawm chromium?
