☞ Differences between Elements,Compounds and Compounds

-----------------------------------------

✒ Elements

• Elements are pure substances.
• Element has only one kind of atom.
• They are represented by symbols.
• In elements smallest particle is atom.
• We cannot divide element into two or more simpler substances by chemical or physical means.

✒ Compounds

• Compounds are impure substances.
• Compound have two or more kind of atom.
• They are represented by chemical formula.
• In compounds smallest particle is molecules.
• We can provide compound in two elements by chemical means.

✒ Mixtures

• Elements or compound just mixed together to form a mixture.
• No new compounds is formed.
• A mixture has a variable composition.
• A mixture shows the property of the constituent substances.
• The constituents can be separated fairly easily by physical methods.

✒ About Elements

• Elements constitute the simplest chemical substances in which all the atoms are exactly the same.
• Example :-

1. Aluminium (Al)
2. Oxygen (O)

✒ About Compounds

• Compounds are chemical substances made up of two or more elements that are chemically bound together in a fixed ratio.
• Example :-

1. Alcohol C2H6O
2. Acetic Acid C2H4O2

✒ About Mixtures

• A mixture contains more than one substance mixed in any proportion.
• There are two types of mixture homogeneous mixture and heterogeneous mixture.
• Example :-

1. Sugar Solution
2. Salt Solution

Answer 2

$\huge\mathcal{\fcolorbox{lime}{black}{\pink{Answer}}}$

The difference between compound and mixture plays an important role in the field of chemistry as many people can easily confuse between the two. Moreover, the mixture refers to a substance that has two or more substances mixed together physically.  In contrast, compound means a combination of two or more elements in a definite ratio. Learn more about the difference between compound and mixture to better understand the two concepts.

Definitionofcompound,

refers to a pure form that comprises of two or more substances by way of chemical combination. A difference between compound and mixture can be seen from the fact that compounds are generally homogenous.

Definition of Mixture,

Mixture refers to an impure substance that comprises of multiple physically mixed substances.  Furthermore, a mixture can be either heterogeneous or homogeneous in nature.  Moreover, the ratio of the substances present in the mixture is not of definite quantity and hence can vary.

Difference Between Compound and Mixture,

COMPOUND:-

A compound is the substances that are formed by combining two are more chemical elements.

Compound substances are always homogeneous in nature.

Water (H₂O), Sodium Chloride (NaCl), Sodium Bicarbonate (NaHCO₃), salt, sugar, and baking soda are some of the examples of compound substance.

Compounds are of three types i.e. covalent compounds, a metallic compound, and ionic compounds. Moreover, compounds can also be classified as organic or inorganic compounds based on the presence of the carbon atom.

Mainly pure water is part of the compound.

The only methods that can be separate constituents of compounds are chemical and electrochemical (like extraction).

The ratio of the elements in compounds is always fixed. They contain only one type of molecule. Also, the elements chemically combined.

MIXTURE:-A mixture is a substance created from two or more matter that can be separate with the help of physical methods.

Nature of Mixture substances can either be homogeneous or heterogeneous.

A mixture of oil and water, sand and soil, sulphur and iron filings, smoke and fog (smog) etc are some examples.

There are two main types of mixture i.e. homogeneous and heterogeneous.

Mixtures fall under impure water.

The constituents of a mixture can easily be separated by physical (like filtration) method.

Whereas, a mixture can have a variable composition of substance in forming but the ratio is not fixed nor they are combined via chemical bonds.
