CHEMISTRY Lecture Notes - Lecture 1: Tellurium, Boron, Periodic Trends
Document Summary
A second broad classification of elements based on their qualities is shown in in addition to the division of elements into the s-, p-, d-, and f-blocks. Metals and non-metals are two categories that apply to the elements. Periodic table is occupied by metals, which make up more than. With the exception of mercury, which has an extremely low melting point (303 k vs. 302 k, respectively), metals are typically solid at ambient temperature. The melting and boiling points of metals are typically high. They function well as heat and electricity conductors. They can be hammered into thin sheets to make them pliable, and they can be pulled into wires because they are ductile. Non-metals, on the other hand, are found at the upper right of the periodic. In fact, the properties of the elements shift in a horizontal row from metallic on the left to non-metallic on the right.
