When metals react with other substances, the metal atoms always form positive ions. The easier it is for a metal to form its positive ion, the more reactive the metal is. Metals can be arranged in order of their reactivity. Very unreactive metals, such as gold and platinum, are found in...
The pink column on the left contains the alkali metals (lithium, sodium, potassium, and so on), which are relatively reactive metals (you probably know that some of them react violently with water, for example, to produce explosive hydrogen gas). If you know where a certain element sits ...
If you don't have the chart of the activity series handy, you can also use trends in the periodic table to predict the reactivity of a metal or nonmetal. The most reactive metals belong to thealkali metalselement group. Reactivity increases as you move down the alkali metals group. The in...
What are the most nonreactive metals? What is the densest chemical element? What is the most metallic element? What is the heaviest alkali metal? What are the heavy metals on the periodic table? What is the heaviest alkaline Earth metal?
What are non-metal elements? What is the most reactive nonmetallic chemical element? What are the heavy metals on the periodic table? What is the chemical element tin? Which element has the highest atomic number? Which metallic chemical element has the symbol W?
Metals are good conductors of heat and electricity. They are elastic in nature and are known as metalloids as they have properties of both metals and nonmetals. They can be hammered into sheets or wires. Metals come from the earth's crust and are found in ores, minerals, and rocks....
English: The main method of extracting metals from their ores is through reduction, often using carbon in a blast furnace for metals less reactive than carbon, or by electrolysis for more reactive metals.Chinese: 从矿石中提取金属的主要方法是还原,通常对低于碳活性的金属使用碳在高炉中进行还原,而对...
Thermite process : When highly reactive metals such as Sodium, Calcium, Aluminium etc., are usedas reducing agents they displace metals of lower reactivity from thecom-pound. These are exothermic reactions. The amount of heat evolved is so large that the metals produced in molten state. ...
