Densities of elements

The melting point, boiling point, and density of element 107, as well as some other properties, are not known because of the small number of atoms produced.

When we assume that the first minerals crystallized from a magma, a liquid rock mass, then the movement of the crystals in the magma will mainly be determined by their densities. Light minerals will rise to the surface, whereas heavy ones will sink. A number of densities of elements are listed in table 7.3 which will give you some idea of the occurrence of the various elements in the different earth layers. Please bear in mind that compounds are and were formed during the transport in magma and that this can lead to drastic changes in density. 

The densities of elements solid at room temperature, except P, are x-ray densities, rounded off, from pp. 46-56 of Vol. 3 of [G.l l]. Densities of gases are from Metals Handbook (Cleveland American Society for Metals, 1948). 

The continuum domain is generally replaced by a series of interconnected subdomains or elements. We must then determine which types of elements are appropriate for a given problem and the density of elements required to sufEciently approximate the solution. 

Elements A and B are both in the same group. One element is in the second period and the other is in the fifth period. The density of element B is greater than the density of element A. Which element is in the second period Explain your answer.

Figure 2.11 I The density of elements in their solid states is plotted as a function of atomic number. Here density is in units of kg/m. The various colors represent the different periods (rows) in the periodic table. Notice how the same general pattern repeats as we move across each row the density is low at the left-hand edge of the row (Group 1), increases through a maximum, and then decreases as we continue to move from left to right across the table. (Only those elements that exist as solids under ordinary conditions are shown.)...

Symbol of element the elements marked with an asterisk have no stable isotopes. Density of elements with boiling points below 0°C is given in g/l.

The more the difference of the specific density of elements and their chemical interaction are weaker, the liquation influence is greater. As a consequence, the EMF measurements do not... 

In general, densities of liquids are known more precisely than those of solids (which may have imperfections in their microscopic structures). Also, densities of elements and compounds are known more precisely than densities of materials with variable compositions (such as wood or rubber).
