Due to one unit more nuclear charge and two binding electrons for Magnesium atom.
Because there are a higher amount of delocalised electrons.
Magnesium, calcium, sodium, lithium, uranium, plutonium can be flammable - depending on the temperature and the physical form. Titanium is flammable at high temperature.
Sodium metal and magnesium metal have metallic bonds. They do form an alloy which also contains metallic bonds.
Not it's not. Sodium is an Alkaline Metal, and Magnesium is an Alkaline Earth Metal, therefore Sodium is more reactant than Magnesium. It is because Alkaline Metals are more reactant than Alkaline Earth Metals.
as a displacement reaction has to occur when the metal is higher in the reactivity series thatn the metal in the salt. With your question this is not the case as sodium is higher than magnesium and so nothing will take effect.
No, sodium is a metal.
Magnesium
At room temperature sodium is a soft metal.
No, Magnesium is a solid metal, melting at 922 K.
Magnesium is a solid at room temperature.The only metal that is a liquid at room temperature is Mercury.
Magnesium is more reactive than copper because if you study the periodic table, you will be able to find out that Magnesium is more reactive.Also, coins are made out of copper, they choose copper because it is cheap and extremely unreactive.Furthermore, I've done an experiment to find out that Magnesium is more reactive than Copper by putting both elements into Water/Acid.
Magnesium, Iron, Copper,sodium and potassium
