QuestionChemistry
Identify the elements correctly shown by decreasing radii size.
A > B means A is larger than B
Select one:
$\bigcirc$ A. $\mathrm{N}>\mathrm{Bi}$
$\bigcirc$ B. $\mathrm{C}>\mathrm{N}$
$\bigcirc$ C. $\mathrm{Cl}>\mathrm{Br}$
$\bigcirc$ D. $\mathrm{K}>\mathrm{Rb}$
$\bigcirc$ E. $\mathrm{Cu}>\mathrm{Au}$

Step 1:I'll solve this problem step by step, focusing on atomic radii trends.
Step 2:: Understand Atomic Radius Trends
Atomic radius depends on several factors: - Atomic number - Electron shell configuration - Position in periodic table
Step 3:: Analyze Periodic Table Trends
The general trends for atomic radius are: - Down a group: Radius increases (more electron shells) - Across a period: Radius decreases (more nuclear attraction)
Step 4:: Evaluate Each Option
- $$\mathrm{Au}$$ will have larger radius
- This statement is FALSE - Both are in period 2 - This statement is FALSE - Both are in group 17 - This statement is FALSE - Both are alkali metals - This statement is FALSE - This statement is FALSE
Final Answer
None of the statements are correct about atomic radii.
