They use chemical equations.
Atomic symbols are used to represent elements, a negative (-) and a psoitive (+) represent electrons and protons, respectively. Chemicals or other compounds are often written as a combination of atomic symbols with subscripts to indicate the presence of multiple atoms.
The periodic table of elements
The symbols used for the elements are the same worldwide. This enables scientists to communicate their ideas with other scientists throughout the world even if they can't speak the same language. :)
No, quite the opposite. An octet of electrons would make the atom stable, and therefor unlikely to react with most elements.
Scientists suggest Mendeleev left gaps in the periodic table because Mendeleev knew the elements existed; however, was unable to prove it.

The periodic table of elements
Chemical elements are formed in the Universe by stellar nucleosynthesis.

Argon is chemically inert due to the presence of completely filled orbitals. So it is does not react with other elements at STP.
At that time, scientists knew some of the properties of more than 60 elements. However, no one had organized the elements according to these properties; making it harder for scientists to understand how elements interact with each other.
it's a warning. It may indicate the presence of a rock, dam, wreck or other danger
The Symbols provide a shorthand method for representing elements and compounds, and how they react with each other. The formula's represent compounds.
definitely our future scientists will invent more and more new elements which r very useful for mankind. Why cant it may be out of earth..! It may be from moon or some other alliean planet.
Scientists know where everything; you, me, this computer, all of it, they know where it came from. Everything is formed from the two parent elements, Hydrogen and Helium. These two elements form all other elements. And to form any other elements, they need extreme energy. The only place to get this amount is from a star. So to answer your question. All water came from stars.
No. Xenon is chemically inert. Hence it does not combine with other elements and is not found in food materials.
