An element x belong to 3rd period and a group 13 of a moderm periodic table determine the valence electron and valency of x and also find molecular formula of the compound formed when x reacts with a element y ( atomic no 8 )
the last answer wont it be x2y??
why it is x2y3??

I think The Element is aluminum
configuration =2,8,3
valency =3
react with y element is oxygen
Al2O3
Al have charge 3 and o=2
Al. O.
3. 2.
Al2O3
configuration =2,8,3
valency =3
react with y element is oxygen
Al2O3
Al have charge 3 and o=2
Al. O.
3. 2.
Al2O3
maksednoobie:
o= -2 rite??
yes but formula bnane K bad yeah nhi likhte
we wont rite the cation and anion??
we write like mg2+ o2- then mgo
but al is 3 rite so 2 and 3 wont get cancelled rite
we should always switch valency while writing equation?

Element is Al(2,8,3)
There are 3 valence elctrons
Valency is 3
IT WILL FORM ALUMINIUM OXIDE WITH FORMULA AL2O3
