Physical Properties of Elements -
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.
-
Density increases from left to right upto middle in a period and increases down the group in the periodic table. Graphite is less dense form of carbon thus the order of density is:
Mg < C(graphite) <B <Al
Therefore, Option(3) is correct
