Figure 1. Schematic representation of the packing of the atoms and the electron distribution in the four types of solids. Ionic. Ionic materials are those that are brittle and that conduct electricity when molten but not as solids. Melting points range upwards from about 500°C. Examples are...
218K Learn about Niels Bohr's atomic model and compare it to Rutherford's model. Explore how to draw the Bohr model of hydrogen and argon, given their electron shells. Related to this QuestionWhat is the group number and number of valence electrons for: \\ 1. potassium? 2....
In stead of a single wire when two different material wires are joined to form a by junction circuit and the junctions are maintained at different temperatures, higher potential difference is developed across the junctions. The arrangement of two different metal wires to form by junction is known...
