Tus lej atomic yog tus lej ntawm protons hauv ib atom ntawm ib yam. Hauv peb qhov piv txwv, krypton tus lej atomic yog 36. Qhov no qhia peb tias ib qho atom ntawm krypton muaj 36 protons hauv nws nucleus.

Kuj paub, muaj pes tsawg protons nyob rau hauv lub nucleus?

Nyob rau hauv cov ntaub ntawv muab, tus naj npawb atomic ntawm lub atom muab yog 15, yog li nws nucleus muaj 15 protons . Tus naj npawb ntawm protons thiab electrons yog tib yam hauv atom thiab qhov ntawd yog qhov ua rau nws nruab nrab.

Tsis tas li ntawd, koj yuav nrhiav tau tus naj npawb ntawm protons rau lub atom li cas? Tus naj npawb ntawm protons, neutrons, thiab electrons hauv atom tuaj yeem txiav txim siab los ntawm cov txheej txheem yooj yim.

  1. Tus naj npawb ntawm protons nyob rau hauv lub nucleus ntawm lub atom yog sib npaug rau atomic tooj (Z).
  2. Tus naj npawb ntawm cov electrons nyob rau hauv ib qho nruab nrab atom yog sib npaug rau tus naj npawb ntawm protons.

Kuj Paub, pom dab tsi hauv lub nucleus ntawm lub atom?

Cov Nucleus : Center of ib Atom . Cov nucleus , uas ntom ntom nruab nrab ntawm lub atom , muaj ob qho tib si protons thiab neutrons. Protons muaj tus nqi zoo, neutrons tsis muaj nqi, thiab electrons muaj qhov tsis zoo. Ib qho nruab nrab atom muaj cov lej sib npaug ntawm cov protons thiab electrons.

Puas yog protons thiab electrons tib yam?

Tiag tiag cov proton thiab electron suav ntawm atom yog sib npaug tsuas yog thaum lub atom yog nruab nrab nyob rau hauv tus nqi. Peb lub atomic particles ntawm ib lub atom yog cov protons , uas nqa ib tug zoo nqi, lub electrons uas nqa tus nqi tsis zoo thiab cov neutrons uas tsis muaj nqi.
