Orbital

He used the concept of electrons circling around a nucleus in orbitals to create the planetary model. Today, the modern atom model is the cloud model. The electrons still revolve in orbitals, but it is now known that these orbitals are not an exact measure, they are simply the places where an electron is most likely to be. This concept has a basis in probability. Also, there are different orbitals, known as the s, p, d, and f orbitals. Each type carries a different number of…

through the resonance effect than the inductive effect. Resonance usually beats induction. The benzene ring is represented by the Kekulé structure to demonstrate the resonance effect. The resonance effect operates through  bonds and adjacent p-orbitals, and the strength of the resonance does not diminish with distance. This is unlike the inductive effect which operates through  bonds and it diminishes with distance. Hence, the order of reactivity of RX to SN1 can be modified as follows:…

alternative reaction pathway. In redox reaction, the key chemical event is the net movement of electrons from one reactant to the other. The oxidation state of atoms are changed. Transition metal is used as redox catalyst due to the availability of empty d-orbitals and the ability to change its oxidation state. Transition metal ions with different oxidation state have different electronic configurations. This allow them to interact in a specific fashion with different organic…

The laws state: orbits of planets are elliptical, the orbits of planets glide in equal areas and times, and the square of the orbital period is proportional to the cube of the orbital radius. These laws pertain to that of the Earth and Mars orbiting the Sun in the movie. Because of the gravitational pull of the Sun this causes the planets to orbit it. This gravitational pull then causes the planets to orbit…

leucotome. A leucotome looks like an ice pick and is used for psychosurgery. He called this procedure the trans orbital lobotomy (Norris,2005). Even though this procedure was simple; the risks of the procedure were dangerous. This procedure could cause infections, seizures, and death. This surgery required the leucotome to be tapped through the orbital bone. One it is through the orbital bone it was brushed through the prefrontal cortex (Gallea,2017). This severed the pathways in the frontal…

The periodic table is a very identifiable symbol in everything science. There is one hanging in almost every chemistry class. But, the one we know is not what it always was. Before our modern periodic table there was the periodic table that Dmitri Mendeleev constructed. There are many differences and similarities between the Modern Periodic Table and Mendeleev’s Periodic Table. Just for example, the modern periodic table arranges elements in order of increasing atomic number. Mendeleev’s ordered…

used to solve existing problems on Earth such as poverty. Conversely, space technology is the catalyst to form other technologies and innovations that are beneficial to our society. For example, the first satellite, 'Sputnik', used to study the orbital measurements of earth had provided new knowledge to develop satellites that are used for telecommunication, navigation…

which project on the nuclear symmetry axis [5]. Since only the collective nuclei have symmetry axis, K values are only found in those collective nuclei, or deformation nuclei. Therefore, K-isomer is the nuclear level states lying on the collective orbital with long lifetime [2]. The most famous discovery of K-isomer was found in 178Hf [5, 6], which has K=16 and 1.31y long lifetime. The configurations of K-isomers are expected to have larger than three quasiparticles [5].Therefore, learning…

The Atomic Theory The Atomic theory is just another law or principle of science, its the very foundation of all that science includes! The laws and principles of science were able to be tested because of this theory! We are going over everything about the atomic theory including its beginning, the history of the atomic theory, and why it is so important in the first place. We will also go over the many models produced by scientists over the years and why they were right or wrong and then…

Extension class for free each quarter and was able to transfer his free class to me. This opportunity has allowed me to take aerospace classes that have taught me skills that are applicable in industry. I took a systems engineering class and an orbital mechanics class. In the systems engineering class, I learned the role of the systems engineer is to plan out the logistics of the spacecraft and take into account all the specificities that come with building and designing a spacecraft based on…
