Verified step by step guidance1
Step 1: Understand the definition of an element. An element is a pure substance that consists of only one type of atom. It cannot be broken down into simpler substances by chemical means.
Step 2: Understand the definition of a compound. A compound is a pure substance formed when two or more different elements are chemically bonded together in fixed ratios.
Step 3: Recognize that elements contain only one kind of atom, while compounds contain atoms of different elements bonded together.
Step 4: Note that compounds have properties different from the elements that compose them, due to the chemical bonds and fixed ratios between atoms.
Step 5: Use this understanding to evaluate the statements and identify the one that correctly distinguishes an element from a compound based on their atomic composition and bonding.
