Scientists first laid down the basic constitution of a metal. Metals are composed of ions surrounded by electrons. Experimenting on the ion's bonding properties and its attraction to electrons generated the properties of metals.
The physical properties of metals depend on this metallic bond.
hard, silver, shiny.
The data from Franklin's X-Ray pattern enabled Watson and Crick to build a model that explained the three dimensional structure and chemical properties of DNA.
a model
It helps explain metallic bonds.
The model used to explain the components and properties of the plasma membrane is called the fluid mosaic.
The current model is impossible. It was made to fit the more advanced properties of matter but failed to explain and was even refuted by the basic irrefutable properties of matter such as visibility and tangibility. Had Rutherford's gold foil been mostly empty space most of it would have been non existent, but instead all of it was there, he could see it and he could touch it, the radiation went through SOMETHING because SOMETHING was definitely there. The only way this current model could be possible is if visibility and tangibility were simply fragments of our imaginations and I highly doubt that.
Properties of metals as high boiling point, high melting point, malleability, ductility, electrical conductivity, thermal conductivity, lustre are explained by the theory of metallic bonds.
Many properties of electronmagnetic waves can be explained by a wave model. However, some properties can be explained by a particle model.

The photoelectric effect is a phenomena that can only be explained by the particle model.

The relational database model organizes data into relations or tables with rows and columns, providing a clear structure for data storage. It supports the concept of primary keys to uniquely identify each record in a table and foreign keys to establish relationships between tables. Additionally, it ensures data integrity through constraints like referential integrity and data normalization.
