Question

Give 5 examples of elements,compounds and mixture.​

Answer 1

Answer:

Note that an element:

consists of only one kind of atom,

cannot be broken down into a simpler type of matter by either physical or chemical means, and

can exist as either atoms (e.g. argon) or molecules (e.g., nitrogen).

A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together. Note that the two nitrogen atoms which comprise a nitrogen molecule move as a unit.

Compounds

Microscopic view of molecules of a compound (gas phase).

Microscopic view of the molecules of the compound water (gas phase). Oxygen atoms are red and hydrogen atoms are white.

Note that a compound:

consists of atoms of two or more different elements bound together,

can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means),

has properties that are different from its component elements, and

always contains the same ratio of its component atoms.

Mixtures

Microscopic view of a mixture of two elements and a compound (gas phase).

Microscopic view of a gaseous mixture containing two elements (argon and nitrogen) and a compound (water).

Note that a mixture:

consists of two or more different elements and/or compounds physically intermingled,

can be separated into its components by physical means, and

often retains many of the properties of its components.

Answer 2

Answer:

Element: The atoms of an element are similar in their properties. For example iron, copper, aluminum, gold, etc.

Compound: When two or more atoms combine through a chemical reaction in a fixed ratio, a compound is formed. For example, sugar, glass, salt, soap, etc.

Mixture: Mixture is a substance that is formed when two or more compounds or elements are mixed in any ratio. For example- sherbet, air. sand, etc.
