Si-28- Protons: 14 (atomicnumber)Neutrons: (mass tooj-atomic tooj) 28- 14 = 14 Electrons: 14 Si-29- Protons: 14 Neutrons :(mass number-atomic number) 29- 14 = 15 Electrons: 14 Si-30- Protons: 14 Neutrons : (ntau tus lej-atomicnumber) 30- 14 = 16 Electrons: 14 3.

Ib yam li ntawd ib tug yuav nug, dab tsi yog cov protons neutrons thiab electrons ntawm silicon?

14

Tsis tas li ntawd, muaj pes tsawg protons neutrons thiab electrons puas Silicon 28? Tus lej atomic yog sib npaug rau tus lej ntawm protons nyob rau hauv lub atom, yog li ntawd silicon muaj 14 protons . Nyob rau hauv ib tug nruab nrab hom, tus naj npawb ntawm protons sib npaug tus naj npawb ntawm electrons yog li ntawd silicon tseem muaj 14 electrons . Tus lej loj yog tus lej ntawm protons ntxiv neutrons , yog li ntawd 28 – 14 protons sib 14 neutrons.

Tib neeg kuj nug, pes tsawg protons neutrons thiab electrons puas Silicon 29?
