An atom has protons and electrons. The protons are placed in the nucleus of the atom while the electrons are situated in the orbital shell of the atom. The way these electrons are positioned is known as the electron configuration. Each shell can hold a...
Counterfeiting today has become a huge problem. The food we eat to the apperal we wear, a wide range of products can be imitated. Almost every country on the map has been a victim of this epidemic. Every one of us might have some or...
Introduction The p-block of the Periodic table consists of groups 13, 14, 15, 16,17 and 18. The elements in the p-block have their outermost electrons in the p-orbital of their shells, hence they are called p-block elements. The p-block consists of solids and gases, and...
We can clearly see the Periodic Table everywhere. It is one of the most important and successful chemistry discoveries to date. To make the completed and latest periodic table, there are a lot of scientists and chemists who have been involved. One of the chemists...
Kinetic Theory and 4 Types of State Kinetic Theory is a description of the properties of atomic particles in different states such as solids, liquids, and gases. In these various states, the atoms possess different energy levels, and the movements of the particles, including the...
Was the Atomic Bomb an Effective Usage of Strategic Bombing? On August 14, 1945, after the atomic bombing, Japan surrendered to the Allied states in World War II. To this day, there are arguments as to whether the usage of the atomic bombs was necessary...
J.J. Thomson was born on December 18, 1856, in Cheetham Hill, England, near Manchester. His father was a bookseller who planned for Thomson to be an engineer. When an apprenticeship at an engineering firm couldn’t be found, Thomson was sent to pass his time at...
Dielectric polarization occurs when a dipole moment is formed in an insulating material because of an externally applied electric field. When a current interacts with a dielectric (insulating) material, the dielectric material will respond with a shift in charge distribution with the positive charges aligning...
Abstract The existence ofsecond-order structural phase transition in the SnSe at a pressure of10GPa has been proved theoretically. The calculation is performed using the plane-wave pseudopotential approach to density-functional theory within the local-density approximation (LDA) withthe help ofthe ABINIT software package. Theabrupt change inbulk module...
Studying atoms has been a big deal for understanding matter and the universe. Just think about it—modern tech, medicine, and energy would be nowhere without knowing about atomic properties, structures, and reactions. As a college student, I find it super interesting to see how our...
