What is elements compound and mixtures?

Answer 1

In an element, all the atoms are of the same type. That is, they all have the same number of protons in their nuclei (atomic number). A sample of an element cannot be separated into two or more components that have different chemical properties . (Isotopes don't count because they don't have different chemical properties.

In a compound, atoms of different elements are connected into molecules or arrayed into crystals, but each molecule has the same number of atoms of each type in the same arrangement, and each crystal has the same types of atoms arrayed in the same pattern. A compound can only be separated into two or more components with different properties by a process that involves a chemical change.

In a mixture there are pieces or molecules of several different compounds, or uncombined atoms of different elements, which can be separated from one another by means that do not involve chemical change.

Answer 2

Firstly , ELEMENT: well element is a substance which is made up of same type of atoms...... for example if we talk about Carbon ,so it is an element made from the atom having 6 protons, 6 neutrons and 6 electrons.....

Now COMPOUND: The substance that is formed by the chemical reaction of two or more elements is known as compound.

MIXTURE: A combination of two or more components that don't undergo chemical change...

so from the above explanation , we got to know that if two or more substances undergo a chemical change or in other words if two substances are united by a chemical reaction is compound and if chemical reaction does not take place , then it's a mixture. and if there is no chemical change then definitely that two substances can be separated from each other .

Answer 3

2 elements are gold and iron. 2 compounds are water, and CO2. 2 mixtures are vinegar and lemonade,
