Interpretation: To determine the subatomic particle which plays the most important role in chemistry.
Concept Introduction: A particle that would be smaller than even an atom would be known as a subatomic particle. Protons, electrons, as well as neutrons, are the 3 subatomic particles that make up an atom in most cases.
Answer to Problem 113A
An essential subatomic particle is electron.
Explanation of Solution
The three subatomic components of an atom are electrons, protons, and neutrons. The nucleus contains protons and neutrons, and the nucleus is surrounded by electrons.
The characteristics and chemical properties of any element are decided by the no. of valence electrons which are basically the outermost electrons. Chemistry deals with the characteristics, make-up, and structure of substances, as well as the changes they go through when they react. So, in chemistry, mainly reactions occurred between two substances are studied.
Thus, the electron was the initial subatomic particle to just be identified, and it eventually turned out to be the one that was most crucial for understanding the
