What characteristics of petroleum make it a valuable resource?

Petroleum stores energy from the sun and is carbon based, this characteristics make it a valuable resource.

Explanation:

Petroleum, a non-renewable fossil fuel has been in great demand as it makes transportation faster. Also we can convert petroleum to different types of liquefied petrol, gasoline and other igniting agents.

Fossil fuels are valuable energy sources because they contain hydrocarbon and other carbon-based materials. From light into heat into electricity, the energy saved with coal and oil arises from the sun, as they arose as plants and animals.

Along with being used as igniting agent, petroleum can also be used for generation of electricity, washing clothes in dry wash, as a lubricant in some of the automobile parts. Also it is used in sports equipment, manufacturing machines as lubricants, carpeting and other every day uses are there for petroleum.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
