The Atomic and Nuclear Structure of an Atom The atom has three main components the protons‚ neutrons‚ and electrons. The protons and neutrons make up the nucleus‚ while the electrons are found outside the atom’s nucleus. Each component of an atom has a charge to it. The protons have a positive charge. The electrons have a negative charge‚ and the neutrons have a neutral charge. The atoms also have a charge. For example hydrogen can be negative‚ positive or neutral. These are called

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

and doctors based off their weight is an issue that could affect how people are treated morally‚ professionally‚ and equally. A study tested 310 third year medical students from 25 different states‚ regardless of age‚ race‚ or gender. The students were given images of over-weight and “thin” (I assume people in shape) persons and were asked to pair them with either positive or negative words. Over 50 percent of the students tested had a moderate to strong unconscious weight bias and more than half were
