• Element Made up of one type of atom
• Compound Made up of two or more different atoms
• Mixture Made up of two or more different materials
• Periodic table It´s an organizational system for elements
• Solution The solute and the solvent together
• Solute This is the substance that dissolves e.g (sugar or salt etc.) (fel kell oldani)
• Solvent This is the substance that solute (salt/sugar etc.) (Òldószer) (Víz)
• Atomic Number The number of electrons (-) and protons (+)
• Atomic Mass Atomic Mass - Atomic Number = How many neutrons it is
• Filtration Filtration is used to separate an insolube solid and a liquid. Filtration involves the use of a sieve or filter paper.
• Evaporation It involves heating the solution until the solvent (the liquid) evaporates, leaving the solute (the solid) behind.
• Distillation (destilláció) Distillation can be used to separare a soluble solid and it´s solvent or two liquids that mix. It´s based on the differented boiling points of the differente substances.
• Chemical Reaktions A new substance is created. This substance is different from the ones you had befor the reaktion happened. Not easily reversed - at the end of the reaction it is difficult to get back the substance you stared with.
• Protons + (same size as the neutrons)
• Neutron (same size as protons)
• Electrons - (smaller than protons and neutrons)
• Shell / Orbits The circles around the atom.
• Neucles (Kärna)
