An Experiment on the Measure of an Electron's Ratio to Its Mass
Introduction: The object of this lab was to determine the measure of the ratio of an electron to its mass. This is done by accelerating a stream of electrons through a measured potential difference. The stream of electrons moves through a uniform magnetic field. It is perpendicular to the velocity of the electrons. The path...

An Introduction and an Analysis of the Static Electricity
Introduction Electric charge on an object is often called static electricity. Objects charge up because they gain or lose electrons. The electron is the smallest part of the atom. The electron carries a fixed negative charge. Every atom has a positively charged nucleus surrounded by electrons. An atom is uncharged because...

Electrostatic Discharge
Electrostatic discharge (ESD) is the transfer of electrons from one object to another. You probably know ESD better as static electricity, or static shock. When you walk across carpet and then shock yourself touching something metal, this is ESD.You experience ESD far more than you might think. The transfer of a static char...

An Overview of the Experiment, Heat Transfer Rates
Science Investigation: InsulationIntroduction My investigation is to find out the rate of which heat transfer happens. Heat transfer is a process in which energy in the form of heat energy is exchanged between materials that are at a different temperature. Heat is generally transferred by conduction, convection, radiati...

How Hair Color Can Affect the Amount of Static Electricity It Creates
My topic is all about how hair color could affect the amount of static electricity it creates. Static electricity is very important to us because we see it, make it and pass it on. Static electricity is everything we see is made up of tiny little parts called atoms. The atoms are made of even smaller parts. These are calle...

An Analysis of Electron Flows in a Series and Parallel Circuits
In a series circuit Electrons flow along a single path through 2 or more loads before returning to source. Law #1 - any break in a series circuit stops the entire electron flow (a break or loose connection can prevent electrons from flowing) Law #2 - when there are two or more loads in a series circuit, the voltage...

The Life and Literary Career of Joseph John Thomson (1856-1940)
Joseph John Thomson (1856-1940) J. J. Thomson was born in cheetham, Manchester. On December 18, 1856. Thomson is known as the man who discovered and identified electrons. He studied at Owen's college, Manchester in 1870. In 1876 he studied in at Trinity College, Cambridge as a minor scholar. In 1884-1918 at the age of...

The Explanation of Electron Pair Repulsion Theory and Different Shapes of Molecules
Electron Pair Repulsion Theory: The electron pair repulsion theory states that the electron pairs in the valence energy level of an atom repel each other, and therefore are arranged as far apart as possible. For example, H2O: Due to this theory, different molecules with different amounts of pairs of electro...

The Science of Atoms
Atoms are basic building blocks of matter, and cannot be divided. Atoms are made up of three types of particles, protons, neutrons, and electrons. Protons and neutrons can be found in the nucleus. Protons have a positive charge, and neutrons have no charge, they are neutral. Electrons can be found in orbitals around the nuc...

An Analysis of the Electromagnetic Theory of Electrons as Defined by Lorentz
As a matter of fact, Einstein had used this fact by applying the Electromagnetic theory of electrons as defined by Lorentz. This subsequently led to the emergence of geometry of space as well as the curvature of space that provided an explanation to the motion of bodies that are in a gravitational field. The first postulate...

An Understanding of Electrons
There are two types of atoms that engage a chemical reaction. They are anions and cations, or in one word – ions. To understand the principles by which separate atoms bound into the compounds we will need to know the terms the atomic radius and the ionic radius. The atomic radius is the distance halfway across the individua...

An Introduction to the Analysis of Semiconductors
Semiconductors have an electrical resistivity that is in between those of good conductors and those of good insulators. Both silicon and germanium, which are the two basic semiconductors, have four electrons in the outermost electron subshell. In formation of the lattice structure of the silicon or germanium, all the valenc...

An Introduction to Wavelength: The Bombardment of Targets of Heavy Atoms by Fast Moving Electrons
Wavelength: 10-11m to 10-9m Sources: The bombardment of targets of heavy atoms (typically tungsten) by fast moving electrons causes energy levels in the target to change. When the target atoms' excited electrons drop back to their original level, they release fixed quanta of electromagnetic energy. (This is called the ph...

An Introduction to the Dependant Variable and the Resistance of the Wire
The dependant variable is the resistance of the wire. The Key Variables are: 1. Wire length 2. Material 3. Wire diameter 4. Temperature 5. Wire Density Wire length: If the length of the wire is increased, then the resistance will increase. This is due to the electrons having a longer distance to travel and so more c...

An Experiment to Determine Resistance in Relation to a Wire's Length
Aim: The aim of this is to investigate how the length of a wire affects the resistance of it. Prediction:           I predict that the longer the piece of wire, the greater the resistance will be. This is due to the idea of the free moving electrons being resisted by the atoms in the wire. In a longer piece of wire, the...

The Processes Caused by Hydrogen Bonds
Hydrogen bonds are extremely strong bonds which join molecules of relatively small mass. This peculiarity creates the unique properties associated with substances with hydrogen bonding, especially in H20.         In most compounds, the polarity of its elements has a negligible effect on the dipole forces which connect them....
