What is the periodic table trend for density?
Density also displays a periodic trend – atomic density increases from top to bottom but varies less significantly as one moves from left to right across a period.
What is the trend of density down the group?
Hence density increases down a group as size increase down the group. First group elements are generally the largest. Larger the size larger is the density because there is large increase in mass with considerable increases in volume. Hence density increases down a group as size increase down the group.
Why does density increase down a group?
As we down in a group then its size increases and also volume of the atom increases as the number of electrons and protons increases. So, on moving top to down in a group, the atomic density generally increases.
What is carbons density?

Is density on the periodic table?
Here is a table listing the density of elements of the periodic table. The values are for density around room temperature, except as noted….Density of Elements of the Periodic Table.
| Element Name | Density (g/cm3) |
|---|---|
| Indium | 7.31 |
| Iodine | 4.94 |
| Iridium | 22.65 |
| Iron | 7.874 |
How does density change down Group 1?
The densities of the Group 1 elements increase down the group (except for a downward fluctuation at potassium). Atomic radius increases down a group, so the volume of the atoms also increases. Fewer sodium atoms than lithium atoms, therefore, can be packed into a given volume.
Does density go up or down?
Density is mass divided by volume. As you heat something up, the volume usually increases because the faster moving molecules are further apart. Since volume is in the denominator, increasing the volume decreases the density.
Which is the densest element?
Osmium
It is the densest of all the elements and is twice as dense as lead. Osmium has only a few uses….
