CO 2 is a compound because it is two different elements bonded. Nitrogen N 2 is a molecule. Water H 2 O is a compound. Ozone O 3 is a molecule. Sugar C 12 H 22 O 11 is a compound. Compound Examples Just in case the difference is still a little fuzzy, you can look at a few more examples of compounds. Difference Between a Molecule and Compound Your head is swimming with atoms, compounds, and molecules. Molecule Compound What they are two or more atoms bonded together two or more different elements bonded together Structure group of atoms bonded matter in complete shape i.
All compounds are molecules. Visibility not visible to humans visible to humans Example oxygen you breathe O 2 table salt NaCl.
Molecule vs. Compound vs. Element vs. Mixture Chemists like to throw around a lot of different terminology. What are atoms? Do atoms have color? Question 0b What is an atom? Is there a difference between a molecule and an atom?
See all questions in Everything is Made of Atoms. Chemistry Ionic Bonds Ionic vs. Molecular Bonds. Jun 1, Explanation: A molecule is two or more atoms chemically bonded to each other. H2 is a molecule since it has two atoms But not a compound since they are the same atoms. Chemical Structures The properties of elements and compounds are determined by their structures.
Electrostatic Forces Electrostatic forces hold atoms in molecules. Determine how charged matter interacts. Properties of metals and nonmetals Metals Nonmetals Physical Properties Good conductor of heat and electricity Poor conductor of heat and electricity Malleable - can be beaten or deformed without cracking; pliable Brittle Ductile - can be made into wire Non-ductile Lustrous Not lustrous, may be opaque or transparent Solid at room temperature except Hg and a few other metals that are liquid at or near room temperature Solid, liquid, or gas at room temperature Chemical Properties Usually have valence electrons Usually have valence electrons Tend to lose valence electrons Tend to gain electrons.
