Nyob ntawd yog 45 neutrons hauv ib Selenium atom.

Tom qab ntawd, Selenium 55 muaj pes tsawg neutrons?

Lub npe	Selenium
Atomic Number	34
Atomic Mass	78.96 atomic mass units
Tus naj npawb ntawm Protons	34
Tus naj npawb ntawm Neutrons	45

Tsis tas li ntawd, muaj pes tsawg ions muaj selenium? Yog li, ua selenium los ua ib tug ruaj khov molecule, nws yuav tsum xav tau txais 2 electrons. Yog li, tus naj npawb ntawm Ion yog -2.

Hauv qhov no, pes tsawg neutrons nyob hauv selenium?

Selenium (Se). Daim duab ntawm nuclear muaj pes tsawg leeg thiab electron configuration ntawm ib tug atom ntawm selenium-80 (atomic tooj: 34 ), qhov feem ntau isotope ntawm lub caij no. Lub nucleus muaj 34 proton (liab) thiab 46 neutrons (xiav).

Yuav ua li cas koj nrhiav tau cov neutrons?

Nco ntsoov tias lub nucleus ntawm ib lub atom yog tsim los ntawm protons thiab neutrons . Thiab cov tus lej ntawm cov khoom uas muaj nyob rau hauv lub nucleus yog hu ua loj tus lej (tseem hu ua atomic mass). Yog li ntawd, rau txiav txim tus tus naj npawb ntawm neutrons Hauv atom, peb tsuas yog yuav tsum tau rho tawm tus naj npawb ntawm protons los ntawm pawg tus lej.
