Assignment: You have been asked to tutor a student in chemistry. This student has been legally blind from birth. You have been asked to describe for the student a word picture of the structure of an atom. Include in this word picture, the parts of the atom, your idea of where the electrons are physically located and describe these locations, and any other pertinent facts needed to complete the description of an atom. My guess is a minimum of 500 to a 1000 words would be required. I need footnotes and a works cited page for any references you used. This description needs to be typed, a 12 point font of either Arial or Times New Roman, and printed for ease of reading and grading.

Explanation / Answer

An atom is the smallest entity of an element. It cannot be broken down any further. Consider an atom (a circleular picture) of which the size varies from 1 to 5 Angstrom and consists of three basic subatomic particles. These particles are referred to as protons, neutrons and electrons. Protons and neutrons reside in the central part of an atom picture called the nucleus. These two particles consituted most of mass of an atom. Electrons which reside on the outside of the nucleus in an atomic picture revolves around the nucleus and is equal to the number of protons in an atom. An atom is neutral in its form. When it looses or gains electrons it gains a positive or a negative charge. The negatively charged electrons are attracted towards the positively charged protons by a net coloumbic force of attraction. when two atom have same electrons and protons but differ in the number of neutrons, they are referred to as isotopes.
