Question

Difference between Elements, Compound and Mixture.​

Answer 1

Answer:

Explanation:

Elements:

• Elements are the purest form of a chemical substance and are composed of only one type of atom.  
• In other words, all of the atoms in an element will have the same number of protons.  

• Please note that a chemical composed of two or more of the same type of element (H2, O2, etc.) are also considered elemental forms as well.
• EG: H2, O2, N2, etc...

Compounds:

• A chemical compound is a chemical that is composed of at least two different types of elements.  
• These elements are combined together in fixed proportions and structures to produce a single type of unique particle.  
• Like an element, a compound is considered a pure substance (meaning there is only one type of particle in the substance).
• EG: H2O, NaCl, etc....

Mixtures:

• A mixture is a combination of two or more different chemical compounds or elemental substances.  
• It is not a pure substance, but a combination multiple particles.  It can be separated into different type of particles.  
• There are two different types of mixtures, homogeneous and heterogeneous.  
• In heterogeneous mixtures, you can see the two different types of substances with your eye.  
• In homogeneous mixtures, you cannot see the two different substances (they appear as a single phase to the eye).

Answer 2

Answer:

Element: Pure substance consisting of one type of atom. Compound: Pure substance consisting of two or more different atoms. Mixture: Two or more different substances not chemically combined.
