Which statement is most likely true? ernest rutherford’s experiment led to the nuclear model of the atom. ernest rutherford’s experiment established the plum pudding model of the atom. robert millikan’s postulates form the most accepted theory for the atomic structure. robert millikan’s results had little impact on determining of the charge of an electron.

Ernest Rutherford’s experiment led to the nuclear model of the atom.

The statement which is mostly likely to be true is “Ernest Rutherford's experiment led to the nuclear model of the atom.”

Explanation

J.J. Thomson's "The plum pudding model" of the atom. In order to confirm the plum pudding model , Rutherford performed the gold foil experiment.

But it lead to prediction of new model of atom termed as nuclear model.

This is because, the gold foil experiment indicated the presence of heavy positively charged particles in the center of the atoms and the negatively charged electrons are revealed to surrounding the positive charge.

This heavy positive charged particles in the center is termed as nucleus of the atom leading to the formation of Nuclear model of atom.

So the first statement is only true. The remaining statements are false, as plum pudding model was established by J.J. Thomson and not by Rutherford and also, the Millikan's postulates were not the most accepted theory for atomic structure but oil drop experiment result by Millikan has a great impact on determining the charge of electrons stating the last two statements also false.

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.
