Apoorav Joshi Mr. Yagar Chemistry 10C 12/7/2015 The Newest Elements There have been many elements that have been discovered in this world. The two latest elements that have been discovered are ununquadium and ununhexium. Ununquadium is element number 114 on the periodic table. It was given the official name of flerovium by the IUPAC in 2012. Ununhexium is element 116 on the periodic table. It was given the official name of livermorium by the IUPAC in 2012. There are two other elements that have

Particles in Atoms The following section will be describing the atom and all of the particles that make it up. It will start off with what protons, neutrons, and electrons are. This will describe where they are in the atom and what their relative sizes respective one another are. This section will end off with the charges of all of these particles and the total number of all of these particles for every element inside of the carbon family. The entire section will be based off of the particles that

Towards the end of Gabriel Garcia Marquez’s Chronicles of a death foretold, the protagonist, a newly graduated student is sent to a small high school in Columbia to share with the hoi polloi the wisdom he gleaned through his years of research. He posed a rhetorical question that took the crowd by surprise. The protagonist was captivated by the knowledge world, a web crisscrossed by seemingly mystic - and dazzlingly complex - relationships. But he did put his finger on quite a puzzle: Why should one

OMRI is based on the Overhauser effect that enhances the amplitude of the NMR signal of the solvent water protons while the ESR transition of the dissolved paramagnetic solute is saturated [9,19-22]. The enhancement of the proton polarization, of the NMR signal of the 1H nuclei (I = 1/2) of water molecules with couplings to an unpaired electron spin S = 1/2 of a dissolved free radical [43,44], is defined as: (1) where is the expectation value of the dynamic nuclear polarization, is

There doesn’t exist a single definition of the term “scientific method.” In broader perspective, scientific method can be explained as a systematic process of asking a question, stating a hypothesis, conducting relevant experiments, analyzing the results and making a conclusion. A relevant example based on the scientific method is the discovery of X-Rays. The man credited for the discovery of the X-Rays was physicist Wilhelm Röntgen. The “Röntgen experiment” consisted of studying a Crookes tube

Neon is a chemical element. Neon was discovered by two chemists named Sir William Ramsay and Morris W. Travers in the country of England. Ramsay and Travers discovered this element in the year or 1898. The word “neon” is a Greek word that means “new”. Neon was discovered through the studies of liquefied air. This element belongs to the “noble gases” group in the periodic table. The symbol for this element is ‘Ne’. Neon is in period two. The atomic number of neon is 10. The atomic mass of neon

hydrogen atom nucleus which has a single proton and is a spinning charged particle. The human body is made up of 70% water, which is hydrogen and oxygen. Those hydrogen nuclei (protons) spin inside the body, creating their own magnetic field. They are orientated randomly and cancel each other out when no field is applied. When the patient is placed inside the MRI, protons will align parallel or antiparallel with the primary magnetic field. There will be more protons in parallel (low energy) than in anti-parallel

electric charge and a mass slightly larger than that of a proton. Protons and neutrons constitute the nuclei of atoms. Since protons and neutrons behave similarly within the nucleus, and each has a mass of approximately one atomic mass unit, they are both referred to as nucleons.[5] Their properties and interactions are described by nuclear physics. The chemical and nuclear properties of the nucleus are determined by the number of protons, called the atomic number, and the number of neutrons, called

theory is right then the mass of the atom was spread out throughout the atom. The deflection of alpha particles was not consistent with Thompson's theory so Rutherford discarded Thompson's theory. Rutherford then created a model of the atom where the protons were in the nucleus and the electrons orbited around the nucleus. This differs from Thompson's model because Thompson put the electrons inside the nucleus when Rutherford had the electrons floating around the nucleus. Rutherford was always aware that
