Electron

One of the most important scientific discoveries is that of the atom. The Atom is the smallest unit of matter. “Atoms are mostly empty space” (OI/ https://www.thoughtco.com/interesting-facts-about-atoms-603817). It makes up all the four elements. “There are over 100 different kinds of atoms ”(OI/https://www.thoughtco.com/interesting-facts-about-atoms-603817).Over time the theories about the atom have changed a lot, moving from simple to complex. Before 1900, scientists made several…

low concentration (there’s a flow of ions) Electrical activity is the ability for electron to travel within the material. Specific solid material molecule will have free electrons to conduct thus allow electrons to freely move within the solid thus create a flow of electron current. Conclusion, they are mechanically similar because both create a flow of particles (ions, free electrons) that enable the flow of electrons current within…

and a relatively high melting point. Molecules and Sugar molecules are covalent compounds. A covalent compound is made when two or more nonmetal atoms bond. They bond by sharing valence electrons. The shared valence electrons is called a covalent bond. Covalent bonds are formed when two atoms begin sharing electrons. Lauric Acid and Stearic…

atomic number is the number of protons in an element. The atomic mass of Neon is 20.180, which when rounded up will become an atomic mass of 20. The state of matter Neon is mainly in is a gaseous state. The full electron configuration of neon is 1s2 2s2 2p6, and the abbreviated electron configuration is [He] 2s2 2p6. The melting point of Neon is at -248.59 degrees Celsius, and the boiling point is at -246.046 degrees Celsius. Neon has a density of 0.0008999 grams per cubic centimeter ("Facts…

The stories Conducting Solutions, Energy Story, and the video Hands-On Science with Squishy Circuits have all helped me learn a lot more about electricity. The purpose of these sources were to help the reader to understand and inform the reader about how electricity is made. It also showed how easy it is to make electricity. These three sources have many differences and similarities but they all serve the same purpose. In the video Hands-On Science with Squishy Circuits it talks about how easy…

insulator, semiconductor and conductor. Insulator Semiconductor Conductor It has a large band gap. It has a smaller band gap. It has no band gap. It has a higher resistivity. It has a moderate resistivity. It has a lower resistivity. No movement of electron occurs, so the conduction band remains empty. It has enough energy to displace a few of…

Since neon is a noble gas, it has a full outer shell, which means that neon has 8 electrons in each shell and neon has a total of 2 shells. Neon has 3 isotopes and has the electron shell configuration of [ He ] 2s22p6. (“Neon,” 2000). Chemical Reactivity The noble gases are sometimes called the inert gases. This name comes from the fact that these elements do not react straight…

occur, known as plastic deformation. The hardening of materials through the use of deformation in a material stems from the atomic structure of a metallic material. Metals are held together by metallic bonding where electrons are shared amongst atoms so that a "sea" of electrons is created. This type of bonding is not only strong enough to keep the atom together, but because of a lack of bond directionality, dislocations are able to be created and moved without the entire molecule falling…

melting point of -100.98 degrees Celsius and a boing point of -34.6 degrees Celsius. However, at room temperature it is a gas. Chlorine contains 17 protons and 17 electrons and also contains 18 neutrons. The density of the chemical element Chlorine is 3.214 c/cm3. Like every member of the halogen group, chlorine has a tendency to gain one electron and become a chloride ion. Chlorine…

co2 the molecules contain one atom of carbon that is bonded with 2 oxygen atoms. The intermolecular forces causes the small covalent structures to have a low melting/boiling points, they don’t conduct electricity because they don’t have any free electrons or an electric charge overall. • Macro molecules will have large covalent structure compared to the small covalent substances such as h2, co2 and o2; more atoms are present as they are arranged into the giant lattices that’s why they have a…
