Atoms are the most basic building blocks, everything around us are made out of atoms. Atoms are so small that it can’t be found under the finest microscopes. A tiny spec of dust contains millions of billions of atoms! Even though atoms are tiny, but it actually consist of three different particles: protons, neutrons, and electrons. In every atom, electrons move around the nucleus, the combination of protons and neutrons. The idea of an atom was first discovered by the ancient Greeks, they…

Every element has its own symbol ,atomic number ,and atomic mass. The symbol is letters of the element, atomic number is the number of protons, and atomic mass is the mass of the element. The Symbol for Calcium is `Ca’ and the atomic number is 20, and the mass number is 40.078 u. Family. The periodic table is classified into groups and every group(row) has its own properties. Calcium is in group 2 ,and this is the second most reactive group of the periodic table. Each of the elements in…

lab was an edge dislocation where an extra plane of atoms was inserted into the crystal structure. If enough pressure is applied on the material, a permanent deformation stemming from dislocations can 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…

Chromium Chromium was discovered in France in 1797. A man named Louis-Nicholas Vauquelin discovered chromium while experimenting with a material known as Siberian red lead. The name Chromium comes from the Greek word "chroma" meaning "color." Chromium got this name because of the many different colors in the element. This element is hard, metallic and shiny. Chromium doesn't tarnish. Chromium is a metal element. Chromium's symbol is "Cr" and has an atomic number of 24. This metal is the…

The purpose of this lab was to analyze and examine periodic trends of the first 36 elements that are on the periodic table. Trends that were analyzed and examined are the atomic radius (AR) and the first ionization energy (IE) of the 36 elements. The hypothesis for this lab was that the elements that are in the groups that had the highest atomic radius would be in the same groups as those who have the the highest first ionization energy and the groups who have the lowest atomic radius would be…

Albert Einstein's influence on astronomy. Albert had a big influence on Astronomy. He started to study mathematics, he was lured toward calculus around 1891. Albert originally wanted to be a electrical engineer. But he failed to do pass an examination which would have allowed him to study for a diploma at the Eidgenössische Technische Hochschule in Zurich. He made a plan of graduating as a teacher in mathematics and physics. He got his PHD in 1905. He also created the theory of relativity. A…

Early Atomic Experiments Joseph John Thomson conducted an experiment that is known today as the CRT Experiment. The outcome of this experiment was JJ’s discovery of the electron. CRT is an acronym for Cathode Ray Tube, this gives a broad concept of what the experiment is about. The basic components of the experiment include, a glass cylindrical tube with most of the air inside vacuumed out of it, and inside the tube is Electrode for each side. One of the Electrodes is negative and entitled the…

energy is always positive. A light wave is made up of these photons, meaning that are the composition of light itself. With this in mind, photons can hit each other, and do so very frequently. When photons bump into other atoms, much of their energy can get the electrons within those atoms to move much faster. These electrons do not want this additional energy, thus they give off heat so that they may return to stable conditions, and this is why we feel…

Electrons can be core or valence. The core electrons are like nobel gases and the valance are the rest. Like noble gases, core electrons do not react, but valence electrons do. Imagine, if you will, a reaction of sodium with chlorine gas. The sodium gives up a valence electron and chlorine gains one. The compound made is 1:1 Na:Cl. A similar thing happens with potassium and bromine, you get KBr. The electron configuration of sodium is 1s2 2s2 2p6 3s1. The part up to 2p is just like the nobel…

Chlorine The element chlorine is located in the 7th group in the periodic table it is the symbol for CI. Chlorine is a chemical element it has a atomic mass of 35. Chlorine has 17 protons, 18 neutrons, and 17 electrons. The electron configuration for chlorine is 3s2-3p5. Chlorine has a boiling point of 3.16, and is family with halogen. Chlorine was discovered in 1774 by Carl Wilhelm Scheele. He obtained it through the reaction of the mineral pyrolusite manganese dioxide with hydrochloric acid.…
