Explain the key concepts of the atomic theory and the potential uses.

must be 8 sentences long

plz answer will give brainiest

See answer below.

Explanation:

Atomic theory, dating from the nineteenth century postulated by the scientist Dalton, states that nature is composed of discrete units: the atoms. There are precedents to this theory: Law of conservation of mass (Lavoisier), Law of Avogadro Law of defined proportions and Law of multiple proportions (Proust). In summary, atomic theory describes the composition of the atom by protons, neutrons and electrons. The combinations of these elements make up the building blocks and then the molecules. Other points of the theory stand out: atoms of the same element are equal to each other (in mass and physical-chemical properties), atoms of different elements differ in mass and other properties, the compounds are formed in a simple numerical relationship by the union of atoms of the corresponding elements. Regarding the uses of atomic theory, there are applications in the field of nuclear energy, petrochemicals, pharmaceutical industry, development of new materials.

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
