Step 1:I'll solve this step by step following the specified LaTeX and formatting guidelines:
Step 2:: Understand Diatomic Molecules
A diatomic molecule consists of two atoms of the same element bonded together. In chemical equations, these are represented with a subscript 2 after the element's symbol.
Step 3:: Analyze Each Element
- Exists as $$\mathrm{Cl}_{2}$$ in its standard state
Let's examine the characteristics of each element: A. Krypton (Kr): - Noble gas - Exists as a monatomic element - Does NOT form diatomic molecules B. Chlorine (Cl): - Halogen - Forms diatomic molecules C. Boron (B): - Metalloid - Exists as a monatomic element - Does NOT form diatomic molecules D. Beryllium (Be): - Alkaline earth metal - Exists as a monatomic element - Does NOT form diatomic molecules
Step 4:: Identify the Diatomic Element
Based on the analysis, Chlorine (Cl) is the only element represented by a diatomic molecule.
Final Answer
Chlorine
