Kuj Paub, yuav ua li cas yog ib daim ntawv cog lus sib cog lus? Qhov zoo protons nyob rau hauv lub nucleus ntawm ib atom yog nyiam rau qhov tsis zoo electrons ntawm lwm atom. A daim ntawv cog lus Cov ntaub ntawv thaum ob lub atoms txuas rau ib leeg yog lub zog qis dua li ob lub atoms sib nrug. Thaum ob lub atom sib koom lawv cov electrons txhawm rau tsim ib qho daim ntawv cog lus , peb npe a covalent bond.

Ib sab ntawm qhov no, pes tsawg valence electrons puas muaj chlorine atom ua ntej nws sib txuas?

xya valence electrons
