What is the chemical symbol of "Potassium"?
Correct answer: B. K
- A. P
- B. K
- C. Po
- D. Pt
Explanation
Potassium has the symbol K, derived from its Latin name kalium, rather than a symbol based directly on the English name. P represents phosphorus, while Po and Pt represent polonium and platinum. The likely mistake is choosing P by taking the first letter of potassium without considering that P is already assigned to phosphorus.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
