1What is matter? matter is the ingredient that makes up whatever in the universe. Matter has actually mass and takes increase space. Issue is make of atoms. Solids, liquids, gases, and also plasma space all matter. Once all atom that comprise a substance room the same, then the substance is an element. Aspects are made of just one type of atom. Because of this, aspects are dubbed "pure" substances. One atom is the smallest piece of an aspect that still has actually the nature of that element. Because that example, aluminum is a lightweight, shiny metal. If we took a item of aluminum and also cut the into tiny pieces, it would still be aluminum. It would still be a lightweight, shining metal. The smallest item would be dubbed an atom. Atoms room so small they cannot be seen also with a microscope. Atoms consist that a nucleus that has actually protons and neutrons surrounding by electrons exterior the nucleus.2Atoms of different elements can incorporate to make brand-new substances. A molecule is developed when 2 or an ext atoms sign up with together chemically. If atoms combine that room of two or much more different elements, we contact that a compound. All compounds space molecules, but not all molecules space compounds. Once two hydrogen atoms combine with one oxygen atom, it becomes the link water. The oxygen us breathe is actually two atoms that oxygen combined, so that is a molecule of oxygen. We usage abbreviations because that elements. These abbreviations for elements are dubbed chemical symbols. Once two or more atoms combine to form a molecule or compound, the abbreviation is recognized as a chemical formula. The chemistry formula for an oxygen molecule is O2.3The link water has a chemistry formula of H2O. This is prefer the "recipe" for water. It tells us that a water molecule is made of 2 atoms the hydrogen and one atom that oxygen. Oxygen is a gas that us can"t see, hear, smell, taste, or feel. Yet it"s in the air we breathe, and without it, we would certainly die. Hydrogen, additionally a gas, is the lightest problem on Earth. As soon as two atoms of hydrogen join in addition to one atom the oxygen, those two gases make a liquid compound we speak to water.

Water, a liquid at room temperature, is a very different problem from the two gases that it is make of. Many different compounds have the right to be make when different atoms combine.Paragraphs 4 to 5:For the finish story v questions: click here for printableWeekly analysis Books
