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
