Synthetic elements

what differences and similarities elements have with each other. As of the similarities we have to identify the physical properties of the elements and compare them. Also, this analyzes what trends certain elements shared within in the periodic table. Finally, after looking at all the aspects of an element we will make our conclusion. These conclusions will help us to find the unknown elements we have been looking for this whole time. In order to place an element in the right place, we had…

controlled conditions. He identified many different laws, postulates, etc. One of which were his four postulates over the atom. John Dalton’s Postulates include: Atoms are small, indivisible particles that make up matter Every atom of a certain element are always identical in mass and properties Atoms can not be destroyed, created, or changed into other types of atoms during chemical reactions, they may only be…

The origin of the three classes, in The Republic was called the “magnificent myth”. This “noble lie” was that not only was your whole childhood built up of lies, but that mother nature put different metals in your heart which would ultimately reveal your destination. This myth was told to the people so that the rulers could preserve their utopian city, the Kallipolis. The Kallipolis’ divisions of labor were producers, auxiliaries and philosophers. “One man was to do one job, the job he was most…

I am researching the element, boron. The symbol of boron is a just a capital B. The atomic number of boron is 5. Boron’s mass is 10.811 grams. Boron has 5 protons, 6 neutrons, and 5 electrons. The Periodic Table lists elements in numerical order from the smallest atomic number to the largest atomic number. That is why boron is the 5th element on the Periodic Table. It comes after beryllium and before carbon. Boron was discovered on June 30th in 1808. It was discovered by French chemists,…

foods from changing the pH of the digestive system. 4. Define a molecule and a compound. Compare and contrast ionic and covalent bonds. Molecule is the smallest unit of an element or compound, made up of two or more atoms held together by strong chemical bond. Compound is a molecule made up of atoms of two or more elements bonded together. The difference between ionic bonds and covalent bonds are their shape, their state of matter at room temperature, and their melting point. Ionic bonds have…

which an unstable atomic nucleus loses energy by emitting radiation. Each radioisotope decays at its own fixed rate and this is measured in half lives. As discussed in Lesson 6, this is the time it takes for half of a parent element (e.g. uranium) to decay into a daughter element (e.g. lead) [1]. A common method of radioactive dating is ‘uranium-lead dating’. Which looks at the amounts of Uranium and determine how much has decayed…

Many environmental pollutants have been associated with human diseases. Our current knowledge of chemical induced adverse health effects is mainly limited to the toxicity of the individual chemicals. For the majority of chemicals, its individual toxicity is well documented, examples arsenic and skin, lung and bladder cancers; dioxin and chloracne; lead and neurotoxicity; benzo[a]pyrene and lung cancer. The scientific community increasingly recognizes the adverse effects associated with chemical…

periodic table, which is for the most part appeared at the bottom of the periodic table. This element has 67 protons in its nucleus, which implies it is the 67th component on the periodic table. Holmium is pliable, which infers it can be bowed and folded. It is the foremost magnetic component of the periodic table. The name comes from the element lanthanum. The lanthanides are also known as rare earth elements. Although lanthanides are not especially rare, they are very difficult to separate…

Introduction: You're a student at NFVMS sitting in your 8th-grade science class and you're on the verge of sleep until you're suddenly handed a mysterious vial that inside holds a white mixture. You’re told that you have to figure out what is in it using physical and chemical properties to help you! What is a physical and chemical property you may be asking. A physical property is something you can touch, feel, smell, hear, and see so you’re using your human senses. A chemical property is when…

chemical formula of a compound will be determined using the mass of each individual element that is present in a weighed sample of that compound. The chemical formula shows the proportions of elements in a specific compound. This proportion is uniform to all samples of the same compound. Using the mass of each element, the moles of the element in the compound can be found and then compared to that of the other elements. This will create our atom ratio which will lead to our mole ratio. The mole…
