A mixture can be separated by looking at the physical properties of the components of the mixture.
Since salt is soluble in water, it can be added to the mixture to dissolve the salt.
The bar magnet is now introduced in order to remove the iron filings since they are attracted by a magnet.
The solution is filtered to separate the sand from the salt solution.
Lastly, the salt solution is heated to dryness to drive away the water and obtain the solid salt.
Hence the mixture has been separated into its components using their individual physical properties. Option A is the correct answer.

Answer:
Could you provide a diagram?
Explanation:
Non of the above because protons and neutrons don’t mix with each one there
We have to get the relationship between metallic character and atomic radius.
Metallic character increases with increase in atomic radius and decrease with decrease of atomic radius.
If electrons from outermost shell of an element can be removed easily, that atom can be considered to have more metallic character.
With increase in atomic radius, nuclear force of attraction towards outermost shell electron decreases which facilitates the release of electron.
With decrease in atomic radius, nuclear force of attraction towards outermost shell electrons increases, so electrons are hold tightly to nucleus. Hence, removal of electron from outermost shell becomes difficult making the atom less metallic in nature.
Answer:
lose or share electrons in such a way that the outer shells become chemically complete
Explanation:
Most interactions among atoms take place in the outermost shell of each atom. The number of each electron in this shell determines how an atom combines with other atoms to form compounds. When atoms combine they gain, lose or share electrons in such a way that the outer shells become chemically complete.
