Chemistry

• Mixtures are combinations of two or more substances in which each substance retains its own chemical properties.
• Mixtures can be classified into two main types: heterogeneous mixtures and homogeneous mixtures.
• In heterogeneous mixtures, the components are not uniformly distributed, and the different substances can be easily distinguished.
• Examples of heterogeneous mixtures include salad, soil, pizza, and granite.
• In homogeneous mixtures, the components are uniformly distributed, and the mixture has a uniform appearance throughout.
• Examples of homogeneous mixtures include saltwater, air, and sugar dissolved in water.
• Elements are pure substances that cannot be broken down into simpler substances by chemical means.
• Compounds are substances composed of two or more different elements chemically combined in fixed ratios.
• Mixtures are combinations of different substances that are not chemically bonded.
• Examples of mixtures include air (a mixture of gases) and a salad (a mixture of vegetables).
• Non-metals are elements that generally lack the characteristics of metals, such as conductivity and a shiny appearance.
• Metalloids exhibit characteristics of both groups.
• Metals are elements that typically have a shiny appearance, conduct electricity, and are malleable and ductile.
• Examples of metals include iron (Fe), copper (Cu), and gold (Au) Silver (Ag), Aluminum (Al)
• Metalloids have properties that are intermediate between metals and non-metals.
• Examples of non-metals include oxygen (O), sulfur (S), and nitrogen (N) Chlorine (Cl) Hydrogen (H)
• Metalloids share properties/of both metals and Non-metals.
• Silicon (Si), Boron (B), Germanium (Ge), Arsenic (As), Antimony (sb) are examples of Metalloids.
• Homogeneous Mixture it is also referred to as solution.
• mixture is made up of two or more different substances which can be separated by physical means.
• Heterogeneous Mixture It can be further classified either as suspensions or colloids.
• Solution It consists of two components: the solvent and the solute.
