The periodic table
Question
- A. Elements in the same group have similar reactivity.
- B. Elements in the same period have the same reactivity.
- C. All elements are equally reactive regardless of their position.
- D. Reactivity is unrelated to atomic number.
Answer
Elements in the same group have similar reactivity.
Explanation
Elements in the same group have the same number of outer-shell electrons, which influences their reactivity.
Common mistake
Misunderstanding Reactivity Trends
Students often predict that all elements in a group will react in the same way without considering their specific positions within the group.
To fix this, students should analyze the specific element's atomic number and outer-shell electron configuration to understand its reactivity compared to other elements in the same group.
