4 protons, 5 neutrons, thiab 4 electrons nyob rau hauv ib tug atom ntawm beryllium.
Kuj tseem paub yog, lub ntsiab lus twg muaj 4 protons thiab 4 neutrons?
beryllium
Tom qab, lo lus nug yog, dab tsi yog lub cim ntawm lub atom uas muaj 4 protons 4 electrons thiab 5 neutrons? Ib qho nruab nrab atom yuav muaj tib tus naj npawb ntawm electrons yog ua protons . Txij li thaum nws muaj 4 protons , nws yuav tsum muaj ib atomic tus lej ntawm 4 . (Qhov ntawd ua rau nws beryllium.) Txij li nws muaj ib 4 proton thiab 5 neutron , nws muaj loj 9.
Tsuas yog li ntawd, lub ntsiab lus twg muaj 4 protons thiab 2 neutrons?
Yog tias cov kws tshawb fawb suav plaub protons hauv ib lub atom, lawv paub tias nws yog ib qho beryllium atom. Ib lub atom nrog peb protons yog lithium atom, ib lub atom nrog tsib protons yog ib tug boron atom, ib tug atom nrog rau protons yog carbon atom… daim ntawv mus ntxiv.
