Chemical element

his revolutionary work, Newton’s three laws of motion. Leading to Einstein’s theory of relativity describing Newton’s idea of gravity and other hidden forces in depth. Alchemy stimulated Newton’s ideas and triggered his perspective with Aristotle’s elements. Even though it was initially known as a protoscience, meaning that it was formerly an unscientific field that later became an official science, the use of the scientific method in alchemy helped propel its way into becoming a true science.…

The elements sodium and chlorine show emergent properties, because when sodium is alone it's just a metal and chlorine is a poisonous gas. When you combine the two with an ionic bond the emergent properties are shown, because they come together to form table salt, but on their own this wouldn't be possible. 2.1.2) Yes, even though organisms only require it in small amounts it is still essential because it contributes to the organism's development. 2.1.3) If a person has an iron deficiency it…

According to the World Health Organization, mercury and lead are two of the top hazardous chemicals of public health concern. Exposure to these toxicants results in serious damage in human bodies, especially young children. If human consume food or drinks that are contaminated with mercury or lead in their diet, they will cause neurological, physical, and behavioral effects, which are irreversible. The degree of severity depends on the amount of hazards in bodies (“Lead”, 2017 & “Mercury”, 2017)…

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…

Throughout this exhibition, I have created one specific theme—to take you through the technique of gilding and the material of gilt bronze. Gilding or Ormolu is a “decorative technique for applying fine gold leaf or powder to a solid surface such as wood, stone, or metal to give a thin coating of gold.” In this case, the exhibition will revolve around gilt bronze Asian artwork. Let us take a tour through multiple pieces and learn about the gilding technique, and how the material has held up…

The Purpose of Mendeleev’s lab was to try to understand and identify the 9 unknown elements that were given. We had to relate it to Mendeleev’s lab of 1869, using his perspective and his methods. For example , he did things like laying out the elements from lightest to heaviest and by the colors. By studying its physical properties and observing the examples given we could identify the elements that were given. Using his methods really helped me understand his point of view, he used the…

Magnesium is a mineral that can be described in so many different ways. It is almost impossible to name every little thing that magnesium may assist in to help our body function. To start with, magnesium is roughly involved in 300 essential reactions that happen within our body. The adult contains about 25g of magnesium in their body. Magnesium has specific recommended consumption level. If there is not enough magnesium in the body, it can cause multiple problems or illnesses. The same applies…

When using a 100 mL graduated cylinder marked every 1 mL, there should be one decimal places in each reading. The first decimal place is an estimated because the graduated cylinder is marked for every 1 mL. The final definitive number is in the ones place, so the tenth place should be estimated, as the last digit of measurement is usually estimated. For example, on a 100ml graduated cylinder marked every 1 mL, a sample reading would be 75.6mL, three significant figures, because 75 would be shown…

A. Significance Copper is one of the most abundant transition metals in the human body and its redox characteristics make copper an important cofactor in many enzymes. Copper containing enzymes are important for tissue generation, synthesis of neurotransmitters, and catalysis of the electron transfer reactions.1 Because of its diverse functions, copper homeostasis deficiency is linked to many diseases. A prominent example is Wilson’s disease with a prevalence of approximately 1 case in 30,000…

How can one element change the world? Well if it is an element like copper then it can change our whole world? Copper allowed for early humans to build new weapons which could help civilizations to win or lose in battle. Copper allowed for the modern revolution thanks to the unique qualities it has that other elements do not. Copper allowed for things such as the telephone to make long distance calls and cell phones which allow us as humans to talk wirelessly to people in another country. It…
