- Protons and neutrons (correct)
- Electrons and neutrons
- Electrons and positrons
- Protons and electrons
What is the difference between an atom and a molecule?
What is the difference between an atom and a molecule?
- Atoms are made up of two or more molecules while molecules are made up of a single atom
- Atoms are indivisible while molecules can be divided (correct)
- Atoms are not found in nature while molecules are
- Atoms are smaller than molecules
What is a molecule?
What is a molecule?
- A substance made up of two or more atoms that are not chemically bonded
- A group of atoms that share a common electron shell
- A substance made up of two or more atoms that are chemically bonded (correct)
- The smallest unit of matter
Study Notes
Atomic Structure
- Protons and neutrons are found in the nucleus of an atom, which is the central part of the atom.
Atoms and Molecules
- An atom is the smallest unit of a chemical element, consisting of a nucleus and electrons.
- A molecule is a group of two or more atoms that are chemically bonded together.
- The key difference between an atom and a molecule is that an atom is a single unit, while a molecule is a group of atoms bonded together.
- Atoms can exist independently, but molecules are formed when atoms share one or more pairs of electrons to form a chemical bond.
