Kev ruaj khov ntawm hydrides txo qis pawg los ntawm NH3 rau BiH3 Qhov no yog vim a txo nyob rau hauv lawv daim ntawv cog lus dissociation enthalpy Txo tus cwj pwm yog ncaj qha ntsig txog qhov yooj yim ntawm kev poob hydrogen. … Li no, daim ntawv cog lus dissociation zog txo cov pab pawg vim qhov nce hauv nruab nrab atom loj.

Vim li cas cov thermal stability ntawm hydrides ntawm pab pawg 16 txo qis pawg?

Teb: Lub thermal stability ntawm hydrides ntawm pawg 16 lub ntsiab txo qis hauv pawg, piv txwv li, H2O > H2S > H2Se > H2Te > H2Po. Qhov no yog vim M-H daim ntawv cog lus sib txuas lub zog txo qis hauv pab pawg nrog kev nce hauv qhov loj ntawm lub hauv paus atom.

Vim li cas thermal stability ntawm pab pawg 15 hydrides txo qis ntawm kev txav mus rau pawg?

Cov electron ceev ntawm lub hauv paus atom txo qis nrog qhov nce ntawm qhov loj ntawm lub hauv paus atom. Li no nws lub peev xwm los pub ib khub ntawm electrons txo qis yog li txo tus cwj pwm yooj yim. … Yog li, raws li qhov loj ntawm lub hauv paus atom nce, qhov kev ruaj ntseg txo Yog li cov thermal stability txo qis pawg.

Vim li cas thiaj txo tus cwj pwm nce qib 15?

Raws li peb txav mus rau hauv pab pawg 15 qhov loj ntawm pawg 15 lub ntsiab nce ntxiv uas ua rau qhov ntev ntawm daim ntawv cog lus ntawm hydrogen atom thiab pab pawg 15 lub ntsiab kom nce. Qhov no nyob rau hauv lem txo qis lub zog ntawm daim ntawv cog lus ntawm hydrogen atom thiab pab pawg 15 lub caij, yog li ua kom nws yooj yim dua los pub cov hydrogen atom.

Vim li cas qhov pib txo qis hauv pab pawg?

Kev nqis mus rau pawg, qhov loj ntawm atom nce. Thiab vim li no, electron ntom ntawm pawg 15 cov ntsiab lus txo qis. Yog li nyiam pub nyiaj electrons txo qis thiab qhov pib txo qis.
