What is the process in which compounds are converted to oxides by heating them in the air?
You put two compounds in a reaction chamber. The more reactive compound will 'steal' the oxide from the other compound.
How are minerals extracted from their ores?
metals are extracted from their ores according to their reactivity series.firstly, metals that are more reactive that carbon are extracted by electrolysis whic is breaking the compounds down using electricity.secondly, metals that are less reactive than carbon are extracted by reduction in which carbon is added to the metal ore, carbon react with oxygen and the metal remain by itself pure.example: Zinc oxide + Carbon ----> Zinc + Carbon dioxideGold and Platinum are found in nature by themselves.
Why is unsaturated compound more reactive?
unsaturation is mainly due to pi electrons which are less stable than sigma bond electrons present in saturated compounds
Why can oxygen and chlorine form a covalent compound?
Thers a zoo out there! ClO, ClO2, ClO3, and so on see the link These are all covalent compounds, gases, all reactive.
Why do you not find pure samples of highly reactive element in the ground?
Being very reactive these elements react quickly and form compounds.
Fairly reactive metals found as ores?
no because if the metals were reactive then they would react with elements in the air non reactive metals are found in there native state like gold and silver.

What causes chemical compounds to form?
The reaction of two elements that are reactive with each other cause a compound to form. ~Chodeman ;)
Is sodium a compound or element?
Sodium is a compound.

Does alkali metals occur freely in nature?
Compounds, or minerals. The most common is the sodium chloride found in sea water. They are too reactive to be found as free elements.
Are molecular compounds reactive?
yes
How are the very reactive metals high up in the reactivity series extracted from their ores?
reactive metals can often be extracted by electrolysis where there ore is disolved into a solvent and an electric current is passed through.
What happens to the reactivity of noble gases as you go down the periodic table?
Firstly noble gases are very unreactive. There are no known compounds of helium or neon, the first two members group 18. There is a compound reported for Ar but it is very reactive. Krypton has some compounds again these are reactive. More compounds of Xenon are known. Radon is pretty well ignored, its radioactive. You could extrapolate a trend- they get more reactive as you go down the group.
Why is lithium only found in compound form?
Lithium like other alkali metals is very reactive and will form stable compounds with many other molecules.
Why is unsaturated compound more reactive?
unsaturation is mainly due to pi electrons which are less stable than sigma bond electrons present in saturated compounds
