Are superheavy elements really so unstable that there is no point trying to synthesis new elements? This leads to the question: ‘How does the size of an element affect the stability?’ What are superheavy elements? The scientific term ‘superheavy’ means elements that have an atomic number that is heavier than‚ element 101‚ which is Rutherfordium. As they suffer from radioactive decay when exposed to lighter elements‚ they are not naturally occurring. Meaning‚ scientists can only artificially make

Observation of Different Photons when Elements are Heated Introduction: The bright line spectrum is the range of colorful lights that are emitted from an atom in its excited state. A “normal” atom‚ or an atom in its ground state‚ is when all of the atom’s electrons are in their proper energy level. When an atom is in its excited state‚ electrons jump to different energy levels making them unstable. As the electron tries to get back to its respective energy level‚ energy is emitted in the form

2HAB=?A Finite Element Analysis was developed as a numerical method of stress analysis‚ but now it has been extended as a general method of solution to many complex engineering and physical science problems. As it involves lot of calculations‚ its growth is closely linked with the developments in computer technology. Now-a-days a number of finite element analysis packages are available commercially and number of users is increasing. A user without a basic course on finite element analysis may produce

Executive Summary FORDs current method of controlling all aspects of the manufacturing is outdated and is limiting the corporation’s annual results. In order to stay competitive and become efficient again‚ FORD needs to re-evaluate their current supply chain and implement key portions of DELLs vertically integrated supply chain model. A proper implementation will increase information flow between suppliers‚ departments and dealers resulting in a reduction of redundant inventory and focus

Rare Earth Elements in the United States Recently‚ international events have brought attentions to the rare-earth elements. Issues surrounding China’s embargo on rare-earth elements exports have raised major concerns among the heavy buying countries around the world that rely on these resources. China currently dominates the global rare-earth production and exports of the international marketstrade. Devastating impacts may arise if China places a long-term embargo on its rare-earth elements export

silver-white chemical element discovered in 1886 by a French scientist named Paul-Émile Lecoq de Boisbaudran. It wasn’t isolated until a different separation technique (ion-exchange) developed in the 1950s by a Canadian scientist Frank Spedding and his team. This rare element it is never naturally found. It is only made chemically. It can be found in minerals such as xenotime. Dysprosium is a member to the lanthanide family on the periodic table just like all the other rare elements.
