Why is chlorine called chloride?

Chloride is what is created when Chlorine gains an electron and combines with other elements. Chloride is found abundantly in nature and is most commonly known for forming neutral salts such as sodium chloride (table salt), potassium chloride, and calcium chloride. Chloride is needed by all living things for survival.

Answer: Explanation: We write chlorine as CL2 because chlorine is a non metallic gas . Also as chlorine is a gas it occurs in diatomic form as cl2 such as hydrogen(h2).

Why halogens are called halogens?

They were given the name halogen, from the Greek roots hal- (“salt”) and -gen (“to produce”), because they all produce sodium salts of similar properties, of which sodium chloride—table salt, or halite—is best known.

Why do we use symbols in the periodic table?

It's easier to navigate the periodic table and write chemical equations and formulae once you know the symbols for the elements. However, sometimes it's easy to confuse symbols of elements with similar names. Other elements have symbols that don't seem to relate to their names at all! For these elements, the symbol usually refers to an older element name that isn't used anymore.

What are the abbreviations for elements?

In fact, there are eleven of the abbreviations for the elements which don't seem to match the modern name. Those are subtle reminders of the history of the Periodic Table and the process of the discovery of elements over the millennia. Eight of these oddities are Au (gold), Ag (silver), Cu (copper), FE (iron), SN (tin), Pb (lead), Sb (antimony), and Hg (mercury): All were among the elements recognized by the ancient Greeks and Romans, and the abbreviations for those are based on a Latin or Greek term for the element.
