Lub frequencies ntawm lub teeb uas ib atom ua tau tawm yog nyob ntawm lub xeev cov electrons tuaj yeem nyob hauv. Thaum zoo siab, ib qho hluav taws xob txav mus rau qhov siab dua zog qib orbital. Thaum lub electron poob rov qab mus rau hauv av theem, lub teeb yog tso tawm.

Ua raws li qhov no, yuav ua li cas thaum lub atom absorbs zog?

Thaum ib tug electron absorbs zog , nws dhia mus rau qhov siab dua orbital. Ib qho hluav taws xob hauv lub xeev zoo siab tuaj yeem tso tawm zog thiab 'poob' mus rau lub xeev qis. Thaum nws ua li no, lub electron tso ib tug photon ntawm electromagnetic zog . Electron tuaj yeem nqus ib quantum zog thiab dhia mus rau lub xeev excitation.

Tsis tas li ntawd, atoms nqus thiab emit zog li cas? Cov electron tuaj yeem nce qhov zog nws xav tau los ntawm nqus tau teeb. Yog hais tias lub electron dhia los ntawm qhov thib ob zog theem qis mus rau thawj zog theem, nws yuav tsum muab tawm ib co zog los ntawm tawm teeb. Cov atom nqus los yog tawm Lub teeb nyob rau hauv cov pob ntawv discrete hu ua photons, thiab txhua photon muaj qhov tseeb zog.

Ua li no, yuav ua li cas thaum lub atom ua ib qho ion?

Ib atom ua Ion (a) yog tias nws tau txais ib lossis ntau dua electron (s) lossis (b) yog tias nws poob ib lossis ntau dua electron. Thaum nws nce electrons nws ua negatively them thiab hu ua anion. Thaum nws poob electron(s) nws ua raug nqi zoo thiab hu ua cation.

Dab tsi ua rau lub atom tawm hluav taws xob?

Electromagnetic hluav taws xob ua thaum ib atom absorbs zog. Lub zog absorbed ua rau ib los yog ntau dua electrons hloov lawv lub zos nyob rau hauv lub atom . Thaum cov hluav taws xob rov qab mus rau nws txoj haujlwm qub, ib qho hluav taws xob hluav taws xob tsim tawm. Cov electrons hauv no atoms ces nyob rau hauv lub xeev siab zog.
