As shown in Figure 3B, the lattice fringe of the NPs shows a 2.1429 Å distance, which is well indexed with the (002) plane of Ru metal (PDF 88-1734). WebThe two main factors affecting lattice enthalpy are the charges on the ions and the ionic radii (which affects the distance between the ions). The charges on the ions. Sodium chloride and magnesium oxide have exactly the same arrangements of ions in the crystal lattice, but the lattice enthalpies are very different. dwayne benbow baltimore
