c)sulphure....its non metallic

saxenavs: hw

prabal8: Valence electrons of x is 6

prabal8: and u made only 2

saxenavs: ya i know bt u can show...

prabal8: make valence electron 6 and then 2 hydrogen....

h1234devani: then do you know the dot structure??

prabal8: yeah but how would I draw on this keypad of phone

h1234devani: No no need now i got it

h1234devani: thanks both of you☺

saxenavs: structure draw nii ho rha...yha
