| Density | Name | # |
|---|---|---|
| 2.07 g/cc | Sulfur | 16 |
| 2.26 g/cc | Carbon | 6 |
| 2.33 g/cc | Silicon | 14 |
| 2.34 g/cc | Boron | 5 |
Why does density increase down group 14?
Atom size increases moving down the group because an additional electron shell is added. Element density increases moving down the group.
What is the heaviest element in group 14?
lead
The heaviest element in group 14, lead, is such a soft and malleable metal that the ancient Romans used thin lead foils as writing tablets, as well as lead cookware and lead pipes for plumbing. (Recall that the atomic symbols for tin and lead come from their Latin names: Sn for stannum and Pb for plumbum.)
What is special about group 14 on the periodic table?
Group 14 is the carbon family. The five members are carbon, silicon, germanium, tin, and lead. All of these elements have four electrons in their outermost energy level. Of the Group 14 elements, only carbon and silicon form bonds as nonmetals (sharing electrons covalently).
Which has highest density?
Most Dense Element Under ordinary conditions of temperature and pressure, osmium is the element with the highest density. Its density is 22.59 g/cm3. At high pressure, iridium becomes the densest element, with a density of 22.75 g/cm3.

Does density increase or decrease down the 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. But the increase in mass is greater than that of increase in volume so the density which is defined as mass per unit volume will increase generally.
Does density increase across periods?
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.
Why lead has higher density than tin?
Lead has a close-packed face-centred cubic structure and a high atomic weight, which results in a density that is greater than the density of most common metals such as iron, copper, and zinc.
Which of these group 14 elements is the most metallic?
Lead
Lead is the only group 14 element that is metallic in both structure and properties under all conditions.
What are the trends in Group 14?
The Group 14 elements tend to adopt oxidation states of +4 and, for the heavier elements, +2 due to the inert pair effect. Members of this group conform well to general periodic trends. The atomic radii increase down the group, and ionization energies decrease. Metallic properties increase down the group.
What are the physical properties of Group 14?
Physical Properties of Group 14 elements Sn and Pb are soft metals with low melting points, while C and Si are nonmetals and Ge is a metalloid. Melting and Boiling Points: Carbon, silicon, and germanium have extremely high melting and boiling points due to their extremely stable solid structures.
