Magnesium is the most reactive metal among silver, copper, lead, zinc, and iron because it has a high tendency to lose electrons, making it readily form compounds with other elements. Its outer electron configuration makes it easier for magnesium to react with other substances compared to the other listed metals.
Magnesium is the most reactive towards oxygen among the metals listed. When exposed to oxygen, magnesium will quickly form a layer of magnesium oxide on its surface, which gives it a dull appearance.
Radium is the least reactive among calcium, magnesium, strontium, and barium. Radium is a highly radioactive metal that readily reacts with other elements, but it is less reactive compared to the other listed elements.
Among zinc, silver, iron, and lead, silver is the least reactive metal. It does not readily react with oxygen or moisture and is less prone to corrosion compared to the others. Zinc and iron are more reactive, often oxidizing more quickly, while lead has moderate reactivity but still does not match silver's stability.
Gold is the most ductile metal among copper, gold, silver, and nickel. It is able to be drawn out into a thin wire without breaking.
Beryllium (Be) is the least reactive among magnesium (Mg), lithium (Li), and beryllium (Be). Beryllium forms a protective oxide layer that prevents further reactions with air, whereas magnesium and lithium react more readily with oxygen and moisture in the air.
Magnesium is more reactive than lead, copper, silver, zinc, and iron because it has a higher tendency to lose electrons and form magnesium ions. When magnesium reacts with hydrochloric acid, it displaces hydrogen from the acid to form magnesium chloride and hydrogen gas. This reaction is more vigorous compared to the reactions of the other metals mentioned.
Magnesium is the most reactive towards oxygen among the metals listed. When exposed to oxygen, magnesium will quickly form a layer of magnesium oxide on its surface, which gives it a dull appearance.
Sodium is by far the most reactive. It self ignites in air (it is stored in oil), reacts vigorously with water (releasing hydrogen) and reacts explosively in acids-even dilute. But the most reactive metal is Cesium and the most reactive non-metal is Flourine Cesium and H20 will explode...
Potassium is the most reactive metal among the ones listed. It reacts vigorously with water, producing hydrogen gas and forming potassium hydroxide. Magnesium is less reactive than potassium, while silver and gold are much less reactive and are considered noble metals.
Magnesium is the least reactive element among magnesium, chlorine, rubidium, and sodium. It belongs to the alkali earth metals and has a low reactivity due to its stable electronic configuration.
Radium is the least reactive among calcium, magnesium, strontium, and barium. Radium is a highly radioactive metal that readily reacts with other elements, but it is less reactive compared to the other listed elements.
A wide variety of metals are converted to foils, among them copper, gold, lead, magnesium, nickel, platinum, silver, tin, and zinc.
The order of reactivity from most to least is sodium, copper, gold. Sodium is highly reactive due to its low ionization energy, copper is less reactive as it forms a protective oxide layer, and gold is the least reactive among these metals.
Aluminum is the least reactive among sodium, aluminum, and magnesium. This is because aluminum is more stable due to the presence of a protective oxide layer on its surface, which prevents further reactions. Magnesium is more reactive than both sodium and aluminum.
Silver is, then copper, then gold, and then aluminum. Copper is used for wiring because it is cheaper than silver. Aluminum is not used very much anymore because it can be dangerous when installed improperly.
Helium is least reactive element.It forms no compounds.Platinum is least reactive metal.
Silver is the best conductor among these options, followed by copper, then tungsten, and finally, silicon. Silver has the highest electrical conductivity of all metals, making it the best choice for conducting electricity. Copper is also an excellent conductor widely used in electrical applications. Tungsten is less conductive than silver and copper but still used in certain high-temperature applications for its properties. Silicon is a semiconductor, not a good conductor of electricity compared to the other materials listed.
