elementlarni

elementlarni are the fundamental substances that make up all matter in the universe. in chemistry, an element is defined as a pure substance consisting of only one type of atom, characterized by a specific number of protons in its nucleus. the elements are organized systematically in the periodic table, which arranges them based on their atomic number, electron configurations, and recurring chemical properties. as of current scientific understanding, there are 118 confirmed elements, 94 of which occur naturally on earth. the remaining elements have been synthesized in laboratories. elements combine in various ways to form compounds, which constitute the vast diversity of materials we encounter daily. each element has unique physical and chemical properties, such as melting point, boiling point, density, and reactivity. some elements, like carbon, oxygen, and nitrogen, are essential for life as we know it, while others are primarily important in industrial applications. the study of elements and their interactions forms the foundation of chemistry and helps us understand the composition and behavior of the natural world.
