Factors affecting network performance Not all networks are the same. As data is broken into component parts (often known frames, packets, or segments) for transmission, several factors can affect their delivery.
It is sometimes strange to see what elements combine to make a compound. Sodium, a soft metal which fizzes violently when put into water, and chlorine, a poisonous gas, make sodium chloride (NaCl), otherwise known as common salt! The elements are usually arranged in the Periodic Table.
Steel contains carbon in varying amounts. Alkali metals: the family of elements in Group IA of the periodic table. The most reactive of all the metals. Alkaline earth metals: the family of elements in Group IIA Allotropes: different molecular forms of the same element Alloy: a mixture if 2 or more elements.
