Atom graphs illustration

The majority of crystallites observed were 3 or 4 nm In size. In Figure 3, a bar graph Illustrates the size range distribution and a comparison of mass variation for the 3 and 4 nm crystallite sizes. Although only thirty analyses were oiade, overall visual analysis confirmed the presence of hundreds of 3 to 4 nm platinum crystals with negligible numbers less or greater than these dimensions. It appears that slight variations In crystallite diameter and thickness have resulted In a fairly uniform number of platinum atoms per crystallite for the majority of the crystallites analyzed. In order to normalize count rates, the decrease In the field emission Intensity was taken Into account. 

Use human atoms to illustrate half-life. Each student is one atom of a sample of an element that has a half-life of four days. Show how the number of atoms (students) decreases over a 20-day period. As each half-life passes, students who are no longer part of the sample will go to another location. Record the number of atoms (students) left as each half-life passes. See how many students are left after 20 days have passed. Make a graph of your illustration showing number of students (atoms) versus time in days. Compare your graph to graphs that show the decay of a radioactive element. 

The atomic graph for Cl in the pseudo-octahedral geometry of CIF5 is illustrate in Figure 14. It is an irregular octahedron, the positions of the six vertices corresponding to the presence... 

Chapter 6). We note, however, that there is not a smooth increase in the magnitude of these properties as the atomic number increases the metals seem to divide into two sets, Sc-Mn and Mn-Zn with peaks at Ti-V and Co-Ni. and this is well illustrated by a graph of boiling point against atomic number (Figure 13.1). 

Figure 5 gives the variation of the atomic volume in the actinide series, for the room temperature crystal structures as well as for the ccp and bcc high temperature allotropes, which exist for a number of actinides. The graph is based on the lattice parameters of Table 1, which includes also recent results. The marked dip in the curve from Th to Am illustrates the shrinkage of interactinide distance which is linked to the itinerancy of the 5f electrons in this part of the actinide series.
