Science differs from other fields of knowledge in the method scientists use to acquire knowledge and in the special meaning they attach to it. Scientific knowledge can be used to explain natural phenomena and predict future events. The scientific method originated in the 17th century with people such as Galileo, Francis Bacon, Robert Boyle and … Read more
Ancient Period This period covers from primitive man through the ancient civilizations of China, India and Greece and their contemporaries up to 350 BC. The first people who began to use instruments made use of nature as it was. For example, stones, tree branches or animal bones could be used as valuable tools. However, nature … Read more
Chemistry is the study of the properties of materials and the changes they undergo. Matter is anything that occupies space and has mass. All the objects we see around us are material objects. The gases found in the atmosphere are also considered matter even though we cannot see them. The properties of matter correspond to … Read more
What is the pH scale? The pOH scale measures hydroxide ion (OH-) concentration in a solution, inversely to the pH scale. Lower pOH values indicate higher alkalinity, while higher values suggest greater acidity. pH + pOH always equals 14 for neutral solutions at a specific temperature, aiding in acidity and basicity assessment. However, it is … Read more
What is the Electron Configuration? The electron configuration is the summary of where the electrons are located around a nucleus. Each neutral atom has a number of electrons equal to its number of protons. Therefore, these electrons are located in orbitals in an arrangement around the nucleus. The notation indicates that indicates their energy and … Read more
