October 30‚ 2014 Jordan Hollenbeck Juhn Borruel Electron Gun - Effects of a Magnetic Field Purpose: The objective of this experiment is to study the motion of an electron in a magnetic field and to establish (show/verify) a relationship between the magnetic strength and the distance the electrons are deflected. Theory and Procedure: The electron gun is an instrument that consists of an electron source (which emits electrons and focus the stream into a beam)‚ a magnetic coil (which uses a voltage

How many electrons does Mg2+ have? (1 mark) Mg2+ has 10 electrons. A magnesium atom has 12 electrons with 2 of the 12 being valence electrons. Therefore the atom will lose the valence electrons which are located on the outermost shell to stabilize itself (outermost shell) as atoms tend to do what it easiest. Since magnesium lost 2 electrons it becomes positive as it is giving away electrons to stabilize other atoms. Hence magnesium then becomes Mg2+ because it lost 2 of the 12 electrons. Given

As Chemistry Summary of how the atoms have changed throughout the years? One of the first founders of the idea of atoms was called Democritus‚ which was in 430 BC. He argued that there were an infinite number of different types of atoms. They were all different shape however they were made from the same stuff. He describes atoms as indivisible particles and also explained certain natural occurrences such as the existence of elements. Atomos (in ancient Greek) means “that which cannot be further

should be examined and should be the issue. 2.) The differences in energy between these lines is produced by electrons going from high to lowe energy orbits and as a result releasing energy and electromagnetic waves with longer wavelengths. This means that these lines are lower in energy when compared to the ultraviolet line spectrum. In addition‚ the ultraviolet lines indicates that electrons is going from high to low energy thus‚ releasing more energy and shorter wavelengths. 3.) a) 4d 5s

What I hope to gain from College Cardenas 1 College is and has always been one of my biggest accomplishments growing up. My mother was the kind who often spoke about college on a constant basis and about sacrificing to become someone for the near future. Nonetheless‚ it was the main reason we left our home country‚ Cuba. There were many different aspirations that I wanted I to gain by the time I was done with college

Deflection of an Electron Beam by an Electric Field Nicole N Lab Problem 1.4 – February 3‚ 2011 Problem Statement: We were asked to test the design of an electron microscope to determine how a change in the electric field affects the position of the beam spot. The goal is to find out how different variables‚ such as charge of the deflection plates providing a vertical electric field and initial velocity of the electron beam will affect the amount of deflection the electron beam experiences

For example‚ taking weight loss supplements. II. Audience Relevance: It would be peaches and cream if we didn’t have to get up and go work out and eat healthy. Only if we could take a magic pill and it all just go away and you could be the perfect size you want. III. Thesis Statement: Today I will inform
