What is chlorine and how does it have an impact on humans’ health and the environment? Chlorine is a chemical element that was discovered by Carl Wilhelm Scheele in 1774. Its symbol is Cl and its atomic number is 17. Chlorine has the physical form of a diatomic greenish-yellow gas at room temperature and atmospheric pressure. 1. 2. Indeed, its name is derived from the Greek word ‘chloros’, meaning ‘yellow-green’. 3. In the Periodic Table of Elements, Chlorine is found in the P-block, in group…

The examination, called LHCb trial, is one of seven molecule material science indicator tests in the particle smasher. The LHC united several researchers from around the globe to cooperatively think about information from the atom smasher with an end goal to comprehend what happened after the Big Bang that permitted matter to survive and fabricate the universe. In the LHCb test, researchers sent two proton bars zooming at close light-speed around the roundabout quickening…

includes atoms. These atoms all have the same amount of protons. 3. A compound is formed when two or more separate elements combine and mix together. An example is pure table salt. Table salt is created by two elements which are sodium and chlorine. Sodium and chlorine combine and mix together until the end result which is the table salt. 4. Atoms are the units of life that are considered basic. Atoms relate to elements because elements consists of one specific kind of atom and the atoms…

Scientist Contribution Significance Lavoisier (1743-1794) Antonie-Laurent Lavoisier was born on August 26, 1743 in France’s capital city, Paris. One of his major discoveries was the founding of the law of conservation of mass. This law states the weights of reagents and products are conserved through any chemical reactions. This is demonstrated through his combustion experiments. He pointed out that combustion requires air, since the reactants are weighed heavier than its products. This…

Introduction In this lab, the size of atoms and molecules in solids and liquids were estimated by using the cubical and spherical atomic model. The former model was used in a simple experiment that calculated the displacement in water and in this case, Aluminum and Copper were used. The spherical model was performed by finding the amount of amount of empty space within a sample of Lead shot. The molecular size in liquids and solids was found by calculating the density and molecular size of…

The periodic table is a very familiar site for many people, and almost all of us have spent a lot of time staring at it in Chemistry classes during our time in high school or college. The periodic table is an extremely important tool and is a great way to help students visualize a large volume of information about the elements and their relationship with each other. During your time learning about the periodic table you likely didn’t spend a lot of time looking at the elements with an atomic…

Chemistry behind underwater diving Name: Date: Teacher: https://en.wikipedia.org/wiki/Scuba_diving Table of contents Introduction Underwater diving has been a fascination of mankind for hundreds of years yet we have only recently figured out how. This is through the invention of scuba gear. Generally this is believed to be just a large can filled with oxygen which you could use to breathe through. However it isn’t quite that simple. Due to underwater pressure…

Triangulene, a chemical similar to graphene, has long been thought to be unable to be synthesized due to its instability. A team from IBM, however, has figured out a way to create this elusive molecule. Triangulene is a flat molecule made of six carbon rings structured in the shape of a triangle. The problem with synthesizing this molecule is that it contains unpaired electrons in two of its outer carbons. These free electrons cause the molecule to oxidize almost instantly as these electrons…

NUMBER and MASS NUMBER of an atom in terms of sub atomic particles. The atomic number refers to the number of protons in an atom, the mass number refers to the number of protons plus the number of neutrons (Bbc.co.uk 2015). 3. A neutral atom contains the same number of protons and electrons. Briefly explain why. If an atom is to be positively charged, it has to have more protons, conversely, if it is to be negatively charged it will have more electrons, so for an atom to be…

inside of a human body. There are two ways which an MRI scanner takes images of the human body. The two ways are the use of a strong magnetic field and the use of radio waves. There are two ways which MRI scanners work and the first is by hydrogen atoms. How this links within the human body is by the main link of hydrogen protons which are within water molecules. And a common fact of the human body is that it is mostly made of water. The hydrogen protons become associated in a magnetic field.…
