Question
- not all element names come from english or latin words. the symbol for tungsten is w from the german word wolfram. the symbol for mercury is hg from the greek word hydragyrum. use the symbols w and hg to explain the system of symbols for elements. * 57. what does the formula h₂o tell you about the composition of water?
Question 56
Element symbols can be derived from non - English/Latin words. For tungsten (W), the symbol comes from the German “wolfram”, and for mercury (Hg), from Greek “hydragyrum”. This shows that element symbols are not only based on English or Latin names of the elements but can also come from the names of the elements in other languages. The system of element symbols allows for using the first letter (or first two letters, with the first capitalized and the second lowercase) of the element's name in its native language (not just English/Latin) to represent the element, providing a standardized way to denote elements even when their common names have non - English/Latin origins.
The chemical formula \(H_2O\) is a way to represent the composition of water at the molecular level. The symbol \(H\) stands for hydrogen and \(O\) stands for oxygen. The subscript \(2\) next to \(H\) indicates that in one molecule of water, there are 2 atoms of hydrogen. The absence of a subscript next to \(O\) (which is equivalent to a subscript of 1) indicates that in one molecule of water, there is 1 atom of oxygen. So, the formula \(H_2O\) tells us that water is composed of hydrogen and oxygen atoms, and specifically, each water molecule contains 2 hydrogen atoms and 1 oxygen atom.

Element symbols can be derived from the element's name in non - English/Latin languages. For example, W (tungsten) comes from German “wolfram” and Hg (mercury) from Greek “hydragyrum”. The system uses 1 - 2 letters (first capitalized, second lowercase if two) from the element's name (could be in its native non - English/Latin language) to represent the element, standardizing element notation.
