A compound is formed of two element "A" and "B". The atoms of element "A" forms face centred cubic close packing and atoms of "B" occupies all the tetrahedral voids. The formula of compound is ...

Answer»

`AB_2`
`AB_8`
`A_4B`
`A_2B`

Solution :NUMBER of A atoms = 4
`therefore` Number of TETRAHEDRAL VOIDS = 8
`therefore` TOTAL number of B atoms = 8
`therefore A: B = 4:8 = 1:2 implies AB_2`.
