Among the following which has the maximum density?
Phosphorous
Sulphur
Silicon
Aluminium
Density
The density of elements also follows almost the same order as the atomic volume. In moving from left to right in a period, the density increases first and becomes maximum till some middle elements thereafter it starts decreasing gradually.
Value of density(in g/cm3) of given elements:-
1) Phosphorous - 1.823
2) Sulphur - 2.06
3) Silicon - 2.34
4) Aluminium - 2.70
2.70 is greater than others so, Al has the maximum density among given elements.
Hence, option number (4) is correct
