Peb kuj yuav saib yog vim li cas Bromine tsim ib 1- ion thiab yuav ua li cas cov electron kev teeb tsa rau Br - yog ib yam li Nobel gas Argon. Pib nrog, Bromine ( Br ) muaj ib qho hluav taws xob kev teeb tsa ntawm 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5. Thaum twg Bromine tsim ib qho ion nws tau txais ib qho valence electrons.

Ib yam li ntawd ib tug yuav nug, dab tsi yog qhov zoo ntawm cov roj teeb rau Br?

[Ar] 3d¹Â° 4s² 4p5

Ib yam li ntawd, yuav ua li cas koj shorthand noble gases? Ua raws li cov kauj ruam hauv qab no los sau luv luv version ntawm electron configurations.

  1. Kauj Ruam 1: Nrhiav lub caij ntawm lub rooj zaum.
  2. Kauj ruam 2: Rov qab mus rau qhov kawg noble roj uas tau dhau los (atomic tooj).
  3. Kauj Ruam 3: Sau lub cim ntawm cov pa roj zoo hauv cov hlua khi kom pib koj lub teeb tsa hluav taws xob.

Ib yam li ntawd, tib neeg nug, cov ntsiab lus twg muaj lub teeb tsa roj zoo?

Qhov no muab lub hauv paus rau lub ntsiab lus luv luv rau kev teeb tsa hluav taws xob hu ua noble gas configuration. Cov ntsiab lus uas pom nyob rau hauv kab kawg ntawm lub sij hawm lub sij hawm yog ib pawg tseem ceeb ntawm cov ntsiab lus uas hu ua noble gases. Lawv yog helium , neon , argon , krypton ua , xenon , thiab radon.

BR muaj pes tsawg electrons?

35 electrons
