Cov electrodes ntawm txhua cov pa roj tso tawm qhov tshwj xeeb thiab cov yam ntxwv wavelength ntawm photons, uas txiav txim siab xim cov roj yuav ci hauv - neon piv txwv glows liab / txiv kab ntxwv. … Qhov no yog vim argon yog cov roj uas yuav tsum muaj qhov tsawg kawg nkaus ntawm cov hluav taws xob tawm tswv yim kom hnov mob thiab yog li siv lub zog tsawg kawg nkaus

Vim li cas neon teeb liab?

Thaum koj siv qhov hluav taws xob siab rau cov hluav taws xob, cov roj neon ionizes, thiab electrons ntws los ntawm cov roj. Cov electrons no excite lub neon atoms thiab ua rau lawv emit lub teeb uas peb pom tau. Neon eits liab teeb thaum energized nyob rau hauv no txoj kev Lwm cov roj emit lwm xim.

Puas neon tsim teeb liab?

Neon: produces a orange-red light. Siv phosphor-xim iav, neon kuj tuaj yeem siv los tsim ntau yam xim: Argon: tsim lub teeb lavender.

Vim li cas ib lub cim uas muaj cov roj neon ci nrog lub teeb liab liab?

Thaum qee cov electrons khiav tawm ntawm lawv cov atoms, lwm tus tau txais lub zog txaus los ua "zoo siab" … Yog li, txhua tus zoo siab electron ntawm ib lub atom tso tawm cov yam ntxwv wavelength ntawm photon. Hauv lwm lo lus, txhua tus zoo siab noble roj tso tawm cov yam ntxwv xim ntawm lub teeb. Rau neon, qhov no yog lub teeb liab-txiv kab ntxwv.

Yuav ua li cas ua lub teeb liab?

Vim tias txhua lub ntsiab lus muaj cov kab lus qhia meej meej, cov kws tshawb fawb muaj peev xwm txheeb xyuas lawv los ntawm cov xim ntawm cov nplaim taws uas lawv tsim. Piv txwv li, tooj liab tsim cov nplaim xiav, lithium thiab strontium cov nplaim liab, calcium cov txiv kab ntxwv nplaim, sodium cov nplaim daj, thiab barium nplaim taws ntsuab.
