Full Answer
B.Element✓ Correct
Element
An element is a pure substance that consists of only one type of atom, distinguished by its atomic number (the number of protons). Carbon (C) is listed on the periodic table as element number 6. A compound is formed when two or more different elements are chemically bonded (e.g., carbon dioxide, CO₂). A mixture contains different substances that are not chemically bonded.
Common mistakes
✗ Confusing an element with a compound.
