Se konsa, sou premye enèji level, pa gen sèlman yon s-orbital, Et pour orbital sa a chaje yon nivo maksimòm de électrons Et nou ale microscope a configuration de gaz noble la, ansanm ak Idwojèn stab ak gen sèlman de électrons te antoure li yo. an n gade sou yon lòt èstrikti Point Et, an n fè yon sèl fè maryaj gen yon Azòt ladan l. Si mwen gade a moléculaire fòmil, CH3-NH2 m pral yon fwa ankò kòmanse avèk kabòn la nan mitan, ak tout kat valence électrons antoure li konsa. e mwen konnen ke twa hydrogens sou kabòn a

let's look at another dot structure, and let's do one tha has a nitrogen in it. so if i look at the molecular formula, CH3-NH2, i'm going to once again start with the carbon in the center, with its four valence electrons around it like that. and i know that three hydrogens on the carbon so i can go ahead and put three hydrogens each hydrogen has one valence electron, like that. and on the right side, i'm going to think about the nitrogen. i need to find the nitrogen in my periodic table. nitrogen is in Group 5.
