Which of the following elements is represented by the symbol Co?

Copper
Cobalt
Calcium
Carbon

The correct answer is: Cobalt

The symbol "Co" represents cobalt on the periodic table of elements. Cobalt is a transition metal known for its hardiness and magnetic properties. It is commonly used in the production of batteries, metal alloys, and as a catalyst in chemical reactions. Understanding element symbols is crucial for anyone involved in scientific fields, particularly in chemistry and materials science, where knowledge about different elements and their properties is essential for practical applications. The other choices include metals that have distinct and different symbols: copper is represented by "Cu," calcium by "Ca," and carbon by "C." Recognizing these symbols aids in the proper identification and understanding of various elements and is fundamental to succeeding in any related examinations or practical tasks.
