Answer 2

Symbols of Chemical Elements with Relative Atomic Mass Greater than 30

The symbols of chemical elements with a relative atomic mass greater than 30 are as follows:

A) Ci - The symbol "Ci" does not correspond to any known chemical element. It is possible that you may have made a typographical error or are referring to a different symbol.

B) Mg - The symbol "Mg" represents the chemical element magnesium. Magnesium has a relative atomic mass of approximately 24.305 [[1]].

C) P - The symbol "P" represents the chemical element phosphorus. Phosphorus has a relative atomic mass of approximately 30.973 [[2]].

D) F - The symbol "F" represents the chemical element fluorine. Fluorine has a relative atomic mass of approximately 18.998 [[3]].

E) Ne - The symbol "Ne" represents the chemical element neon. Neon has a relative atomic mass of approximately 20.180 [[4]].

To summarize, the symbols of chemical elements with a relative atomic mass greater than 30 are Mg (magnesium) and P (phosphorus). The symbols F (fluorine) and Ne (neon) have relative atomic masses below 30.

Please note that the relative atomic masses mentioned here are approximate values and may vary slightly depending on the source.
