توضیحات

Embark on a journey through the elemental foundations of the universe with "The Complete Guide to the Elements."Tailored for student chemists and inquisitive minds alike, this concise yet comprehensive reference book demystifies the elements of the periodic table.From a brief overview of the table’s structure and significance to detailed profiles on each element—including name, symbol, atomic number, mass, discovery history, physical properties, and applications—this guide makes the vast world of chemistry accessible to all.Whether you're deepening your scientific knowledge or exploring the elements for the first time, this book is your quintessential companion through the universe's building blocks.This is the perfect gift for a budding science student who wants to increase their knowledge and have a quick reference guide on the fundamentals of all the known elements.CLICK the READ SAMPLE to find out more.-----------------------Here's a couple of extracts...HalogensThe Halogen group is a group of highly reactive non-metals located in Group 17 (or Group VIIA) of the periodic table. It consists of the elements fluorine, chlorine, bromine, iodine, and astatine. The Halogens have seven valence electrons in their outermost shell, which makes them highly reactive and able to form salts with metals.The Halogens are characterized by their high electronegativity, which means they have a strong attraction for electrons. They are very reactive with other elements and can form compounds with nearly all other elements on the periodic table. Halogens are also characterized by their ability to exist in all three states of matter at room temperature. Fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids.Halogens are toxic to humans in their elemental form and can cause severe burns or respiratory problems if inhaled or ingested. However, many halogens and their compounds have important uses in industry, medicine, and other fields. For example, fluorine is used in toothpaste and other dental products to prevent cavities, chlorine is used to disinfect water and in the production of PVC plastics, bromine is used as a flame retardant in textiles and plastics, and iodine is used in the production of disinfectants and iodized salt. Astatine is a rare and unstable element with few practical applications.Overall, the Halogen group plays an important role in many aspects of modern society, despite their toxicity and reactivity.SodiumElement Name: SodiumDescription: Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white metal that belongs to the alkali metal group of elements.Symbol: NaAtomic Number: 11Atomic Mass: 22.989Discovered by: Humphry DavyYear Discovered: 1807Physical Properties: Sodium is a soft, silvery-white metal that is highly reactive and easily oxidised in air. It has a low melting and boiling point and is very ductile and malleable, meaning it can be easily shaped or bent without breaking.Melting Point: 97.8°C (208°F)Usage: Sodium is used in a variety of applications, including in the production of soap, paper, and textiles. It is also used as a reagent in the chemical industry and as a coolant in nuclear reactors. Additionally, sodium is a key element in the regulation of water balance and blood pressure in the human body and is an essential nutrient for all living organisms.
