Which of the following statements about elements and compounds is CORRECT?
hard Q9 of 15
Step-by-Step Solution
Step 1: Recall definitions
Elements are pure substances made of one kind of atom; compounds are chemically combined substances.Step 2: Analyze each statement
Elements cannot be broken down chemically; compounds have different properties from elements; compounds cannot be separated physically; only the statement that elements consist of atoms of one kind is correct.Step 3: Explain why others are wrong
Elements are simplest substances; compounds have unique properties unlike their elements; physical separation does not separate compounds.Final Answer:
Elements consist of atoms of only one kind → Option DQuick Check:
Element composition = Atoms of one kind ✅
Quick Trick: Elements are simplest substances, compounds are chemically combined.
Common Mistakes:
- Confusing properties and separation methods of elements and compounds.
