A molecule is a group of two or more atoms held together by
chemical bonds
. A compound is a substance which is formed by two or more different types of elements which are united chemically in a fixed proportion. All molecules are not compounds. All compounds are molecules.
What are the similarities between a compound and a molecule?
| Molecule Compound | Structure group of atoms bonded matter in complete shape (i.e. table salt) | Relationship Not all molecules are compounds. All compounds are molecules. | Visibility not visible to humans visible to humans | Example oxygen you breathe (O 2 ) table salt (NaCl) |

What are some similarities and differences between elements molecules and compounds?
A compound contains atoms of different elements chemically combined
together in a fixed ratio
. An element is a pure chemical substance made of same type of atom. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule.
What is difference between molecule of element and compound?
A molecule is formed when
two or more atoms
of an element chemically join together. And a compound is a type of molecule, in which the types of atoms forming the molecule are different from each other.
What is the difference between a molecule and a compound quizlet?
Molecule:
two or more atoms
may combine to form a distinctive type of particle. Compound: substance composed of two or more chemically bonded elements.
What is the difference between a molecule and an atom?
Atoms are
single neutral
particles. Molecules are neutral particles made of two or more atoms bonded together.
What is the difference between molecules and compounds give examples of each?
Answer: A molecule is a group of two or more atoms held together by
chemical
bonds. A compound is a substance which is formed by two or more different types of elements which are united chemically in a fixed proportion. … An example of a molecule is ozone.
What is the relationship between a molecule and a compound?
Molecules are groups of two or more atoms, but there is a special sub-group of molecules, too. These are compounds, and a compound is a
group of two or more different atoms chemically bonded together
. The key here is that compounds are made of at least two different elements.
What is difference between element and molecule?
The difference between molecules and elements is
elements are always made up of only one type of atom
but molecules can be made up of only one type of atom or more than one type of atom. For example H2 is molecule made up of only one type of atom( Hydrogen). But another molecule CO2 is made up of carbon and oxygen.
What are the similarities and differences between atoms and molecules quizlet?
An atom is the smallest particle of matter and is made of protons, neutrons, and electrons.
Molecules are made of two or more atoms combined together
. You just studied 15 terms!
What is the difference between a compound and a zoetrope?
What is the difference between a compound and a zoetrope? a compound is a new chemical composed of two
or
more chemicals with its own unique physical and chemical properties. Zeotropes are mixtures of two or more chemicals that are not chemically bonded.
How are atoms ions and molecules similar?
Atoms are the smallest unit of matter that can’t be broken down chemically. Molecules are groups of
two or more atoms
that are chemically bonded. Ions are atoms or molecules that have gained or lost one or more of their valence electrons and therefore have a net positive or negative charge.
What’s the difference between a compound and a mixture?
Difference between Compound and Mixture
Compounds are formed because of chemical bonding between two elements
. Mixtures are formed when substances are physically mixed with one another. Compounds are basically of three kinds : Ionic, metallic and covalent.
What is the difference between the molecules of an element and the molecules of a compound class 9?
Molecules of an element contains
the same kind of atoms
,e.g. P4 is a molecules of element which contains all four atoms of phosphorus. Molecules of a compound contains two or more kinds of atoms, e.g. H2O is molecules of compound which contains 2 atoms of hydrogen and 1 atom of oxygen. HOPE IT HELPS YOU!!
What is the relationship between a molecule and an atom?
A molecule is made up of atoms bonded together. So, while an atom is its own separate entity, a molecule is what
you get when those atoms bond together
. These might be the same elements, such as two oxygen atoms bonded together (O2), or it might be different atoms bonded together like water (H2O).
What are the similarities between an atom and an element?
What are the similarities between an atom and an element?
A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons
. An element is a substance that is made entirely from one type of atom.
Which of the following is not a difference between a compound and mixture?
Question: What of the following is not a difference between a compound and a mixture:
Mixtures can be separated by physical means-straining, filtering, or evaporation
. Compounds can only be separated into their constituent atoms by chemically breaking bonds. Mixtures are homogeneous while compounds are heterogeneous.
What’s the difference between Zeotrope and azeotrope?
The terms azeotropic and zeotropic are opposite to each other. The key difference between azeotropic and zeotropic mixture is that
the dew point and bubble point of an azeotropic mixture intersect
, whereas the dew point and bubble point of a zeotropic mixture are distinguishable.
What is the difference between H * * * * * * * * * * and heterogeneous mixture?
A
homogenous
mixture is that mixture in which the components mix with each other and its composition is uniform throughout the solution. A heterogenous mixture is that mixture in which the composition is not uniform throughout and different components are observed.
What is the difference between compound and mixture mention three points?
| Parameter Compound Mixture | Meaning A compound is a pure form comprising of two or more elements in a chemical combination A mixture is an impure substance involving two or more substances that are physically mixed. |
|---|
What is the difference between azeotropic and zeotropic refrigerants?
Azeotropic and zeotropic mixtures have
different dew and bubble curves
characteristics in a temperature-composition graph. Namely, azeotropic mixtures have dew and bubble curves that intersect, but zeotropic mixtures do not. In other words, zeotropic mixtures have no azeotropic points.
What is the main difference between a zeotropic and an azeotropic refrigerant blend?
11. What is the main difference between a zeotropic and an azeotropic blend? Zeotropic has a notable temperature glide and will fractionate ,
azeotropic has a temperature glide
but is minimal doesn’t fractionate under normal working conditions. with zeotropic blends, refrigerant must leave the cylinder as a liquid.
What is the difference between molecular compounds and ionic compounds?
Molecular compounds are pure substances formed when atoms are linked together by sharing of electrons while ionic compounds are formed due to the transfer of electrons. 2. … Molecular compounds are formed between
two non-metals
while ionic compounds are formed between metals and non-metals.
What is the difference between an atom A molecule a compound and an isotope?
All isotopes of a particular element have the same number of protons, but can have different numbers of
neutrons
. If you change the number of protons an atom has, you change the type of element it is. … A compound is a substance made from two or more different elements that have been chemically joined.
What is the difference between an atom ion molecule and compound?
Larger than an atom
, a molecule is a group of bonded atoms. … An element, such as gold, is composed of molecules of only one type of atom, while compounds have different types of atoms. You can tell how many atoms of each kind exist in a molecule or compound by looking at its chemical formula.
