Question

How does the atomic theory explain the reaction in nature

Answer 1

Answer:

ATOMS ARE FUNDAMENTAL UNITS OF MATTER AND ALL ATOMS ARE CONSERVED IN CHEMICAL REACTIONS. IN CHEMICAL REACTIONS, ATOMS ARE REARRANGED AND REGROUPED TO FORM COMPOUNDS (NAME WE GIVE TO MOLECULES FORMED FROM ATOMS). FOR EXAMPLE, TWO ATOMS OF HYDROGEN AND AN ATOM OF OXYGEN REACT TO FORM THE COMPOUND-WATER.

Answer 2

The atomic theory explains the nature of matter by which the universe, galaxies and solar system are formed. Law of conservation of matter is obeyed.

Explanation:

• The Atomic theory of matter was first postulated by John Dalton.

• According to the theory, Each element is made up of fundamental units called ATOMS.
• All atoms present in a given element are identical.
• For example, Gold, Copper, iron, Zinc are individual elements which are having the same atoms.
• Molecules are formed when atoms combine with one another in order to form more complex units.

• Molecules are made up of constituent atoms.

• Water is made up of two atoms of Hydrogen and one atom of oxygen.

• All water molecule is made up of two hydrogen atoms and one atom of oxygen. Their ratio is always 2:1 only.
• Fundamental units of the matter are atoms and all atoms are conserved in chemical reactions.
• In all chemical reaction atoms are rearranged and regrouped to form compounds
