Electron paramagnetic resonance

"Energy Story", "Hands-On Science with Squishy Circuits" and "Conducting Solutions". All very informative sources about electricity and how its conducted. In Energy Story what the author is explaining the basics of the science behind the amazing process that allows us to have electronic instruments that run on this source of energy. The purpose of the article "Energy Story", is to inform the reader about the scientific force behind this process, and what goes on when we flip a light switch. It…

in a solution of metals. These electrons get heated at the same temperature, however the energy that is needed to excite each electron in the different metals is not the same. This means that the energy levels that change are now unstable and need to cool down, and as soon as they are moved into the heat source through kinetic energy, a photon of light energy is created and this excites all electrons. The flames change colors based on the amount of excited electrons and this makes the colors…

more energy from the accelerating voltage. The accelerated particles may be used to bombard suitable target materials to produce radioisotopes. Modern cyclotrons accelerate negative ions towards the outer edge of the chamber stripping the excess electrons off the ions to form positive particles such as a proton which can then be extracted from the cyclotron as a beam. The energy attained by the particle is determined by the size of the vacuum…

The noble gases are the group of elements which are like no other elements. The noble gases are the elements grouped as the last group, group 18. These elements, from smallest to greatest atomic mass, are Helium, Neon, Argon, Krypton, Xenon, and Radon. Group 18 wasn't always called the noble gases. this group used to be called the inert gassses. They changed the name of thisi group because they are not always inert, or chemically inactive. the first element in this group is the element…

Today we might know an atom being the smallest piece of an element that represent an element, but you might not know the whole story. It all being in 1803, when a curious guy, known as John Dalton, who proposed an “atomic theory” with spherical solid atoms based upon measurable properties of mass. Later on Dalton introduced his belief that atoms of different elements could be universally distinguished based on their varying atomic weights. John Dalton's research not only changed the face of…

subatomic particles: electrons, protons and neutrons. For which the Nucleus contains the Protons and Neutrons, while electrons orbit around the nucleus. The atom is a fundamental piece of matter. Atoms are the building blocks of matter and matter builds up the Universe. A Valence Electron is an electron, which is a subatomic particle of an atom. Valence electrons are located in the outermost shell of the atom, these can be transferred to or shared with another atom. Valence electrons are…

The arrangement of electrons is distributed between four orbital’s; S, P, D and F. Each orbital is a different shape and holds a different number of electrons. Orbital S is a circle and it contains two electrons and orbital P has three different shells. One shell is an infinity sign, the next is a crooked infinity sign and the last is shaped like an upright infinity sign. Each shell can hold two electrons which allow orbital P to hold six electrons, orbital D can hold ten electrons, and orbital…

the nucleus, the nucleus contains the protons, which have a positive electric charge, along with the neutrons, which have a neutral charge and is slightly heavier in mass when compared to a proton. Along the outer rings of the atom the electrons orbit, the electrons have a negative electric charge, as well as the smallest mass out of the three. “The nuclear forces” is a common name used to describe the connection between the protons and neutrons in the nucleus. Nuclear stability is the stability…

fundamental unit of a chemical compound that can take part in a chemical reaction. Molecules are three-dimensional entities and therefore should be depicted in three dimensions. My group decided on the claim that as electrons are bonded to a central atom, the greater the electron repulsion, causing an increase in the bond angles. Bond angles are the angles that are formed between two adjacent bonds on the same central atom. We analyzed the information that we discovered on the website that…

A Helmholtz resonator is a rigid container which has an opening to the air surrounding it. A common example of a Helmholtz resonator is a bottle because it has a set volume as well as having an opening which is open to the surrounding air. By considering the Helmholtz resonator as having a neck, such as the neck of a wine bottle, the dynamics of the system may be described. When energy is introduced near the opening of the bottle, for example blowing across it, some of the energy will vibrate…
