Which term describes the abbreviation or short representation of a chemical element?

• A. Atomic number
• B. Atomic mass
• C. Symbol
• D. Periodic table

Answer: (C)

In chemistry, each element has a one- or two-letter symbol that serves as its short representation. This symbol is used in formulas and reactions to stand for the element without writing its full name. For example, hydrogen is H, oxygen is O, sodium is Na, and iron is Fe. The symbol is the concise shorthand that identifies the element in calculations and equations. The other terms refer to different ideas: the atomic number is the number of protons, which identifies the element numerically; the atomic mass is the average mass of its atoms; and the periodic table is the chart that organizes all elements. Therefore, the term that describes the abbreviation or short representation of a chemical element is the symbol.
