Sustainability means meeting present needs without compromising the ability of future generations to meet theirs. It involves balancing environmental health, economic growth, and social well-being. By conserving resources, reducing waste, and protecting ecosystems, sustainability supports long-term planetary health and human prosperity. It’s key to building a resilient, livable future
Science is the systematic study of the natural world through observation, experimentation, and analysis. It seeks to understand how things work by forming testable explanations and predictions. Science covers fields like physics, chemistry, and biology, and helps us solve problems, improve technology, and make informed decisions about our world.
In chemistry, measurement involves determining the quantity of substances using standardized units. Key measurements include mass (grams), volume (liters), temperature (°C or K), and amount of substance (moles). Precision and accuracy are crucial. Tools like balances, graduated cylinders, and thermometers help ensure reliable data for experiments and calculations
Matter is classified based on its composition and properties. It can be a pure substance—like elements or compounds—or a mixture. Mixtures are either homogeneous (uniform, like saltwater) or heterogeneous (non-uniform, like salad). This classification helps in understanding how matter behaves, reacts, and how it can be separated.
Atomic structure describes how atoms are built. At the center is the nucleus, containing positively charged protons and neutral neutrons. Orbiting this nucleus are negatively charged electrons, arranged in energy levels or shells. The number of protons defines the element, while electron arrangement determines chemical behavior and bonding patterns.
The periodic table organizes elements by atomic number and properties. Forces of attraction—like electrostatic pull between protons and electrons—explain trends. Across a period, attraction strengthens as nuclear charge increases. Down a group, added shells weaken attraction. These patterns influence atomic size, ionization energy, and how elements bond and react
