The Size of an atom LAB Introduction: In this particular experiment we are to measure the properties of certain substances using methods that cannot be done with standard measurement tools, such as a ruler, scale, or clock. For instance to find the size of the molecule of oleic acid we shall use an indirect method. […]
Scientists and philosophers took many centuries to develop a precise atomic theory. Over a period of almost 2,000 years, there was a dearth of experiments conducted for verifying and endorsing the theories put forth by Democritus in the fifth century B.C. C. Greek philosopher. In 1803, John Dalton, who saw the atom as a small […]
Introduction The purpose of the flame lab was to identify a set of flame-test color standards for selected metal ions, relate the colors of a flame test to the behavior of excited electrons in a metal ion, observe spectral lines using diffraction grating, and to identify an unknown metal ion by using a flame test. […]
The rates of reaction of Alkali metals and Alkaline Earth meatals are compared in this lab. The pH of each of the ensuing metal solutions are tested and the merchandises of the reaction between Ca and H2O is discovered. The tried elements are sodium. Li. K and Ca and each of them were placed in […]
Ethyl ether was introduced in 1846 as an anesthetic, replacing opium and alcohol commonly used for pain relief. Despite its revelation for the medical profession, it caused undesirable side effects such as nausea and vomiting. Chloroform emerged in the late asses as a more pleasant alternative, becoming popular after Scottish doctor James Young Simpson published […]
Why Do Atoms React? Google Search 1. What is an atom? An atom is the basic unit of a chemical element. 2. What is an element? An element is a substance that is made entirely from one type of atom. 3. What makes an atom unstable (reactive)? The binding energy not being strong enough makes […]
Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It determines several properties of a substance including its reactivity, polarity, phase of matter, color, magnetism, and biological The angles between bonds that an atom forms depend only weakly on the rest of the molecule, I. E. They can be understood as […]
In any case, only one atomic mass can be an integer because of the difference in mass between a proton and neutron, and the fact that the sum of the particle masses for any isotope is not equal to the mass of the isotope. There are different isotopes of the elements. The atomic weight is […]
This page explains what electronegative Is, and how and why it varies around the Periodic Table. It looks at the way that electronegative differences affect bond type and explains what is meant by polar bonds and polar molecules. If you are interested in electronegative in an organic chemistry context, you will find a link at […]
Metals are the least electronegative of the elements. The Palling electromagnetisms for the elements are often Included as a part of the chart of the elements. An Important application of electronegative is in the prediction of the polarity of a chemical bond. Because hydrogen has an electronegative of 2. 1 and chlorine has an electronegative […]
Carbon dating plays a crucial role for archaeologists, geologists, and anthropologists worldwide. Its significance lies in providing essential dates and confirming or correcting existing ones, thereby aiding in the reconstruction of human history. In 1948, while studying at the University of Chicago, he and his colleagues delved into the utilization of carbon-14 in determining the […]
In this paper I will discuss the element called Radon. Â I will explain how and when this element was discovered, its’ physical characteristics, the natural environment of the element and the abundance in which it occurs. In addition, I will describe why Radon is important to humans, and other interesting facts related to this element.Radon […]
Objective: To determine experimentally the water of hydration for the hydrate Borax. Theory: In this experiment, we examined and found the water of hydration of the hydrate borax. Borax is derived from the element Boron, which is a metalloid chemical element with properties between those of carbon and aluminum(95CI). Boron is relatively rare, constituting only […]
Have you ever done the laundry and wondered what was in the detergent you use? Or if you watched a rocket launch into space have you wondered how it can even make it past earth? The answer to those questions is boron (B). Boron is a metalloid element with an atomic number of 5 and […]
Chemical Warfare is using the chemical properties of a substance to your advantage during war. This has been going on for centuries. Even the most basic forms of weapons were used. People have been putting poison on the end of their spears and arrows since they have been around. Over the years, it has also […]
Fossil fuels provide both energy and raw materials such as ethylene, for the production of other substances construct word and balanced formulae equations of chemical reactions as they are encountered. There are three important steps involved: Â Show all reactants and all products in the word equation. Write the correct formula for each reactant and each […]
The big bang theory! The big bang theory was an event that led to the formation of the Universe. Less than a billionth ofa second after the big bang a bubble much smaller than a fraction of an atom forms! It is unimaginably small and unimaginably hot. The temperatures of the universe at that time […]
Gunfire residue (GSR) or firearm discharge residue (FDR) is composed of partially burned and unburned propellant powder. It consists of residues from the bullet’s force, the primer, cartridge instance, the firearm itself, and the pulverization from the propellant that are expelled from spreads in the gun’s working parts. Particles including atoms from the ammo primer, […]
Timekeeping is made possible due to the fact that the counting interval can be done repeatedly without high variation. Although mechanical means for example use of amechanical pendulum can be used in timekeeping, such methods are not as effective as theuse of atomic clock for time keeping. Although there are a number of elements that […]
