Question

Write distribution of electron and valmey of nitrogen,oxygen

Answer 1

Answer:  VALENCY OF OXYGEN= -2

VALENCY OF NITROGEN = -3

Explanation:  AS THE ATOMIC NUMBER OF OXYGEN IS 8

SO,ACCORDING TO DISTRIBUTION OF ELECTRON IN SHELLS'IT'S ELECTRONIC CONFIGURATION IS 2,6.

AS WE KNOW THAT IF AN ELEMENT HAS MORE THAN N3 ELECTRON IN  OUTERMOST SHELL THEN WE CALCULATE IT'S VALENCY BY SUBTRACTING THE NUMBER OF ELECTRON BY 8.

BY USING THIS CONCEPT,

ATOMIC NUMBER OF NITROGEN = 7

ELCTRONIC CONFIGURATION = 2,5

VALENCY OF NITROGEN = 5-8=-3

ATOMIC NUMBER OF OXYGEN = 8

ELECTRONOIC DISTRIBUTION = 2,6

VALENCY OF OXYGEN = 8-6 = -2

HOPE THIS WILL HELP YOU.

THANK YOU
