An elimination reaction can best be described as a reaction in which an elimination reaction can best be described as a reaction in which a hydrocarbon reacts with oxygen to produce co2, h2o, and energy. two reactants combine to form one new product with no extra atoms. a single reactant splits into two products. two reactants exchange atoms to give two new products. a single reactant undergoes reorganization of its chemical bonds, producing an isomer of the reactant.

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.
