Both earth and the planet venus have a large amount of water vapor in the atmosphere, and have extensive volcanic activity throughout history. does this observation support or disprove the inside-out model? supports, because venus is near earth and would have been hit by all the same comets. disproves, because a single observation can discredit a theory. disproves, because data taken on venus is not applicable to earth. supports, because it shows that volcanic activity may be related to water vapor.

I would say it supports the inside out model because both planets are similar.

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.
