Verified step by step guidance1
Understand that atoms are the fundamental building blocks of matter, meaning they are the smallest units that retain the properties of an element.
Recognize that atoms are not composed of molecules; rather, molecules are composed of atoms bonded together.
Clarify that atoms are not the largest units of matter; they are actually very small, with subatomic particles like protons, neutrons, and electrons.
Identify that atoms are made up of protons, neutrons, and electrons, not just protons and electrons.
Conclude that the statement 'Atoms are the smallest units of matter that retain the properties of an element' is the most accurate description of atoms.
