Q: What are the different characteristics of the elements? 1 - its physical properties: density, color, luster, conductors of heat and electricity, nacho machine boiling and freezing. 2 - chemical properties: describe how the interaction of the elements with other elements. Q: How was the order of the elements in the periodic nacho machine table? Depending on their physical properties and chemical. Q: How were classified nacho machine items? nacho machine Classified into: 1 - metals: alkali nacho machine metals, alkaline earth metals, and, and transition metals. 2 - non-metals. 3 - Semi-metals. Q: Locate all of the metals and non-metals and semi-metals in the periodic table? 1 - metals: Take the blue. The alkali metals are located on the left side of the periodic table run under hydrogen nacho machine - and alkaline earth metals are located on the right hand alkali metals directly - and the transition metals are located in the middle of the periodic table. 2 - non-metals nacho machine located on the right side of the periodic table and carrying yellow color. 3 - Semi-metals: Located directly on the left of the non-metals and carrying green. Q: What are the properties of metals and non-metals and semi-metals? A - for metals: its luster and shine - reach heat and electricity - are formed. Alkaline (soft) - alkaline earth (light) - The transition (stiff and react slowly with other elements). - Non-metals: most do not conducts heat and electricity - can not be formed and easy to fracture - does not have the glamor and glitter. - Semi-metals: semi-conductive of heat and electricity conduct nacho machine electricity at high temperatures. Non-form. Q: I remember examples of metals and non-metals and semi-metals? Metals: alkali such as sodium and potassium - alkaline earth such as calcium and magnesium - the transition such as gold, zinc, copper, iron and silver. Non-metals: from gases (oxygen, hydrogen, nitrogen and chlorine) - steel (carbon, sulfur and iodine) of liquid (bromine). Semi-metals: such as silicon and boron. Q: What are some uses of the elements in metals and non-metals and semi-metals? Metals (gold and silver) are used in the manufacture of jewelery - (calcium and magnesium) are essential for living creatures - (iron): in construction - a (for copper) in the manufacture of electrical wiring. Non-metals: (helium) is used in balloons. (Argon) is used in light bulbs. (Oxygen) to breathe. (PCBs) nacho machine in water disinfection. Metalloids: the rest of the semiconductor silicon nacho machine and metals used in the manufacture of machinery and computer chips and electrical circuits. Q: What are noble gases? These gases do not react with other elements in natural conditions. nacho machine It has many uses we mentioned some of them. The noble gases are: helium, argon, neon, ... etc.. These elements are located on the right side of the periodic table. Q: I remember an example of liquid nacho machine metal? Mercury Q: What acids? What rules? Acids: pungent materials and incendiary when touched turning paper sunflower blue to red. And interact with metals consisting of hydrogen gas. Rules: materials with a bitter taste and texture of viscous like soap. The transformation of paper sold to blue red sun. Q: What are some examples of acids and bases? Acids: such as lemon, a weak acid. The carbonic acid and hydrochloric acid, and citric acid. Rules: Like most derivatives soaps, detergents and household cleaners sewer. Q: How can detect acids and bases? 1 - Taste of the methods used, but serious way. 2 - Reagents: material that changes color when you add the acid or the base paper such as sunflower and cabbage juice. Q: How do I know if the acid and base strong or weak? Using pH scale from zero beginner and even No. 14. The materials that are less than seven acids - substances and most of the seven rules. The materials with a pH equal to seven are neutral (not acid nor base) like water. Q: What uses of acids and bases? Acids: strong acids in the manufacture of plastics and tissues. And hydrochloric acid analyzes the food during digestion. Rules: strong bases used in batteries and in the detergent industry. Q: What is a salt? And his own pH? Salt compound nacho machine resulting from the interaction of acid with a base. And number 7 and pH neutral means that it does not like water, acid or base. Such as sodium chloride and magnesium sulfate.
