Similar elements with different applications
The lanthanides are shown in a separate row below the main table. Their chemical similarities can make separation difficult. Differences in optical and magnetic behavior, however, lead to different uses. Comparing neighboring elements helps show why a family of similar elements is useful in many distinct materials.
What the atomic number tells us
Praseodymium has atomic number 59. This is the number of protons in its nucleus. A neutral atom also has 59 electrons. Losing or gaining electrons makes an ion; it does not change the element unless the proton count changes.
The model's rings help count electrons by shell. They are not actual circular paths. A model of one atom and the properties of a whole material are different levels of description.
