[quote author=t.boy007]i guess the element which have variable oxidation number in halogen is astatine.
Reason:it belongs to the d-block orbital..[/quote]very true cos the only elements with variable oxidation states are the transition metals.

mayorall: Whats the percentage composition of oxygen in K2Cr2O7?
Cr =52
k = 39
0 = 16

A.14.20
B.26.53
C.38.09
D.35.37

Cr=52x2=104 , K=39x2=78 ,O=16x7=112 so Rmm=112+78+104=294 %comp.=mass of element / RMM of compound x 100 , 112x100/294=38.09g

mayorall: Which of the following bonding does not involve formation of new compound....
A.dative
B.co-ordinate covalent bonding.

I plan to study PE abroad to support the oil and gas industry of Nigeria professionally after my education. I will also use my knowhow to nurture and mentor the younger ones to achieve professional status.

Good luck.
