1What is matter? matter is the ingredient that renders up every little thing in the universe. Matter has mass and takes up space. Matter is made of atoms. Solids, liquids, gases, and plasma space all matter. Once all atom that make up a substance space the same, then the substance is an element. Elements are made of only one kind of atom. Since of this, aspects are called "pure" substances. An atom is the smallest piece of an element that still has the properties of that element. Because that example, aluminum is a lightweight, glowing metal. If we took a piece of aluminum and cut the into small pieces, it would certainly still it is in aluminum. It would certainly still be a lightweight, shining metal. The smallest item would be referred to as an atom. Atoms are so little they cannot be seen even with a microscope. Atom consist of a cell nucleus that has actually protons and also neutrons surrounded by electrons outside the nucleus.2Atoms of different aspects can combine to make brand-new substances. A molecule is created when 2 or an ext atoms join together chemically. If atoms combine that room of two or much more different elements, we speak to that a compound. All compounds room molecules, however not every molecules space compounds. When two hydrogen atoms integrate with one oxygen atom, it i do not care the compound water. The oxygen us breathe is actually two atoms that oxygen combined, so it is a molecule the oxygen. We use abbreviations for elements. These abbreviation for aspects are dubbed chemical symbols. Once two or much more atoms combine to form a molecule or compound, the abbreviation is well-known as a chemical formula. The chemistry formula because that an oxygen molecule is O2.3The compound water has a chemical formula of H2O. This is prefer the "recipe" because that water. It tells united state that a water molecule is do of 2 atoms that hydrogen and also one atom of oxygen. Oxygen is a gas that us can"t see, hear, smell, taste, or feel. Yet it"s in the air us breathe, and also without it, we would die. Hydrogen, likewise a gas, is the lightest problem on Earth. When two atom of hydrogen join along with one atom the oxygen, those two gases make a fluid compound we call water.

Water, a fluid at room temperature, is a really different problem from the 2 gases the it is make of. Plenty of different compounds can be made when various atoms combine.Paragraphs 4 come 5:For the finish story v questions: click below for printableWeekly analysis Books
