Introduction

Atoms are those constituents of all the matters which are the smallest. Atoms are the main part of the element and the different elements have different atoms. Atoms also contain the sub-atomic particles. Among these sub-atomic particles, the three particles hold the significant importance and therefore are studied more. These sub-atomic particles includes proton, neutron and electron. The elements that are different possess different atoms in terms of difference in the number of these sub-atomic particles. Consequently, the number of subatomic particles in an atom is the basis for the characterization of the atoms elements containing the atoms. Most Continue reading...

Abstract

John Dalton’s interest in meteorology led him to the breakthrough discovery which he has proposed in his Atomic Theory.
John Dalton was a chemist from the England and a meteorologist and physicist. John Dalton is well known for his contribution towards the atomic theory. On the basis of the atomic theory, he is known to be the father of the modern atomic theory. John Dalton was also involved in forecasting the weather. He was among those scientists who liked to place the instruments at home which Continue reading...

1. Cisplatin
Cisplatin is a compound from four ligands – two chlorine atoms and two amine molecules – that are covalently bonded to a central metal ion, which is platinum. This compound has a square planar shape with two similar ligands on one side; that is, the two chloride ions are on the same side of the square. This inorganic compound is currently being used to treat cancer due to its capability to adversely affect the replication process of the cancer cells’ DNA molecules. Accordingly, under aqueous environments, the chloride ligands are readily replaced by water molecules to reduce the stearic Continue reading...

The aim of this experiment is to investigate the reason of poisoning in a patient whether from mineral bottled water and a saline drip by using ICP-MS and ICP-OES.
A patient was found suffered from excessive Sodium levels in his body. A recently given saline drip was assumed to be a reason, so two saline drips have been investigated. Another reason for this toxicity is that the patients may have consumed it through bottled mineral water. To solve the problem, it is necessary to measure the Sodium levels in saline drips. The evaluation of toxic metal is required to Continue reading...

Sun is an important heavenly body that exists in the solar system. Because of its existence, other planets and stars are moving appropriately in their orbits. The sun produces a large quantity of heat and light which is a source of energy for other planets including the Earth. Scientists have worked upon for so many years upon the working of the Sun. how does the sun produce light and heat. How does the sun produce light and heat? How does it provide energy?
The sun is a combination of an ample of gasses, which when combined results in various Continue reading...

Solid and liquid substances expand when heated. This is due to the increased movement of atoms in a heated object. Heat increases the kinetic energy of atoms in a body. The kinetic energy causes atoms to vibrate vigorously about a fixed position in solids. In fluids, the atoms are not fixed and move haphazardly within the fluid. The increased kinetic energy causes the atoms of the fluid to move faster. Increased atom movement causes an increase in volume of substance. This is a paper on thermal expansion, its useful applications and itsnegative effects.
Thermal expansion has both advantages and Continue reading...

Application of X-Ray Crystallography in Drug Discovery

Introduction
X-ray crystallography is a technique that is used in identification of the atomic and molecular structures of a crystal (Dziedzic et al., 2015). The crystalline atoms diffract a beam of incident X-rays to a number of specific directions. Through the measurement of the angles and the intensities of the diffracted rays, an expert in X-ray crystallography is capable of producing three-dimensional images of the density of electrons with the crystal. It is through the establishment of the electron density that the scientists are able to determine the mean positions of atoms in the crystal, their disorder, chemical bonds Continue reading...

Atoms are every bit of you and everywhere in nature. From the food you eat and the air you breathe, atom s behaves as an everyday material you get to used consciously and unconsciously. Human intervention of nature has resulted many great things as well as the not-so-good things. This has enabled us study how things happens and explain the complexity of the designs of nature’s works and used it to our advancement and profit. Today, we are now capable of seeing things up to the atomic level. Scientist has been able to study the electrons, protons and Continue reading...

When objects are heated, they expand, a phenomenon referred to as thermal expansion. Thermal expansion is exhibited in an object heated above absolute zero or -273 degrees Celsius. Thermal expansion is caused by increased atoms movements. Solids are made up of fixed atoms. When a solid is heated, the atoms gain kinetic energy and vibrate about their fixed position. Kinetic energy gained by molecules is proportional to heat energy gained. Hence expansion is directly proportional to heating temperatures. In fluids such as gases, the atoms are more sparsely packed and move haphazardly. Heating in gases causes the free atoms Continue reading...

The absolute temperature pertains to the temperature scale measured in kelvin where the zero on the Kelvin scale pertains to the theoretically lowest attainable temperature. This particular temperature scale was established after the observations of a phenomenon that at any given pressure, the plot of the temperature and the volume of a gas follows a straight line. Even with different pressures, the plot is always straight; furthermore, all plots seem to be directed towards a similar y-intercept which is -273.15 ˚C, that is, the temperature value when the volume is zero – or close to zero (Chang & Overby 144).
Theoretically, Continue reading...
