You are an environmental engineer working at a petroleum “farm” in chelsea, ma. you are responsible to maintain an inventory of the volume of petroleum in each tank and check for discrepancies in inventory. you notice a 20,000-gallon negative discrepancy of unleaded gasoline and you notice a sheen on the stream and into the harbor that abuts the tank farm.
what do you do? who do you notify?
what agencies are likely to be involved in any cleanup. is the sheen related to the discrepancy or could there be another cause?
what are the most important factors in your response?
what are you most concerned about? sensitive receptors? liability to you and your company? legal issues? justify your answers.

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.
