Ntawm no, cov khoom ntawm pawg 2 yog dab tsi?

Cov cuab yeej ntawm Pawg 2 Elements Qhov no pab pawg muaj xws li beryllium, magnesium, calcium, strontium, barium, thiab radium. Ua hauv pab 2 txhais tau hais tias lawv txhua tus muaj ob lub valence electrons, los yog cov electrons uas nyob deb ntawm lub nucleus. Cov valence electrons no feem ntau yog cov electrons koom nrog hauv cov tshuaj tiv thaiv.

Qhov thib ob, dab tsi yog lub cev khoom ntawm alkaline ntiaj teb hlau? Cov khoom ntawm Alkaline Earth Metals

  • ci iab.
  • nyiaj-dawb.
  • me ntsis reactive hlau ntawm tus qauv kub thiab siab.
  • yooj yim poob lawv ob sab sab nraud electrons los tsim cations nrog 2 + nqi.
  • tsawg ntom.
  • cov ntsiab lus melting tsawg.
  • qis cov ntsiab lus kub.

Xav txog qhov no, dab tsi yog lub cev thiab tshuaj lom neeg ntawm Pawg 2 cov ntsiab lus?

Pab pawg 2 muaj mos, nyiaj hlau uas yog tsis tshua muaj hlau nyob rau hauv tus cwj pwm tshaj cov Pab pawg 1 cov ntsiab lus . Txawm tias muaj ntau yam ntxwv muaj ntau thoob plaws hauv pab pawg , qhov hnyav dua hlau xws li Ca, Sr, Ba, thiab Ra yog yuav luag li reactive li cov Pab pawg 1 Alkali Hlau.

Dab tsi yog lub cev muaj zog ntawm pawg 1 cov ntsiab lus?

Cov pab pawg 1 yam yog tag nrho cov mos, reactive hlau nrog cov ntsiab lus melting tsawg. Lawv cuam tshuam nrog dej los tsim cov tshuaj alkaline hlau hydroxide thiab hydrogen. Reactivity nce zuj zus pab pawg.
