Period 4: iron (Fe), cobalt (Co), nickel (Ni).
The symbols of such elements are based on their Latin names. For example, the symbol Fe for iron comes from the Latin ferrum, meaning iron.
See link. It has all the symbols for all the planets.
You may be referring to the elements whose symbols do not match their names. Such symbols refer to names for those elements (or something related) in other languages. Examples: Au (gold) comes from the Latin word aurum W (tungsten) comes form the Swedish word wolfram. Tungsten is still sometimes called wolfram. Na (sodium) comes from the Latin word natrium which itself may come from the Egyptian word natron. Natrium is the modern German word for sodium.
Because there are languages other than English, and elements have different names in those languages. Some of the symbols are taken from those languages instead. Latin is probably the most common; it's responsible for Fe, Na, K, Cu, Ag, Au, Sn, Sb, and Pb (at least... there may be a few others I missed). Tungsten is called Wolfram in some countries, and its symbol W comes from that name.
John Dalton (1766-1844) was a science teacher who also kept detailed records of the weather. He suggested that every chemical element consisted of tiny particles, atoms, which were identical to each other but different from the atoms of other chemical elements. He also gave names and symbols to about 30 chemical elements. However, he thought that atoms were solid spheres, like metal balls, which could be never destroyed. Also, some substances which Dalton believed were elements are now known to be combinations of elements, or compounds.
some elements do not use their first letters of their English names as their symbols. The symbols for these elements may come from the names of the elements in a different language.
No. Most of the symbols for elements are derived from their names in English. Most of the elements were not even known in ancient Greece.
The symbols are universal and the names are different in each language
Symbols are used to shorten the names of the elements.
Symbols come from latin names of the elements. Example: Tungsten(W), W stands for wolfram.
is false
It is filled with the names (or chemical symbols) of elements.
Many elements names are of Greek and Latin words. Some elements are name after where named after countries like France, German ect.
All elements that don't currently have IUPAC systematic placeholder names have one or two letter chemical symbols. So, currently, elements 1 (Hydrogen) to 112 (Copernicium) have one or two letter symbols.
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 any more. Here's an alphabetical list of element symbols with the corresponding element name. Keep in mind that the names for the elements (and their symbols) may be different in languages other than English.
names - atoms
The symbols of such elements are based on their Latin names. For example, the symbol Fe for iron comes from the Latin ferrum, meaning iron.
