Which statement is true for London dispersion forces? A. At any given point in time, a partial charge called an instantaneous dipole can form in a molecule, producing a repulsion between neighboring molecules.

B. Larger atoms require lower boiling points than smaller atoms to overcome the strong intermolecular attraction.

C. The attraction between induced dipole–instantaneous dipole pairs is very strong and permanent.

D. The strength of intermolecular attractive forces is greater in larger molecules than in smaller molecules.

explanation:

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.
