Which of the following options correctly reflect the relationship between dispersion forces and particle size? Select all that apply. Multiple select question. Larger particles are more polarizable and experience stronger dispersion forces. Dispersion forces are strongest for small particles since they can get closer together in space. Dispersion forces tend to decrease with size as larger particles are farther apart and therefore attract each other less. For molecules of similar shape, dispersion forces tend to increase with increasing molar mass.

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.

the answer is 0.42 is that is an option. this question provides no info
