Choose the correct interpretation of this result in terms of the law of definite proportion. the composition of a substance depends on the total number of atoms and not on the composition of the mixture from which it was formed. the composition of a substance depends on the numbers of atoms of each element making up the compound (depends on the formula of the compound) and not on the composition of the mixture from which it was formed. the composition of a substance depends on the composition of the mixture from which it was formed and not on the numbers of atoms of each element making up the compound (not on the formula of the compound). the composition of a mixture depends on the numbers of atoms of each element making up the mixture and not on the composition of the substance from which it was formed.

As per the law of definite proportion which is also called proust's law The composition of a substance depends on the total number of atoms and not on the composition of the mixture from which it was formed.

Like in the preparation of water 2 hydrogen molecule and one oxygen molecule reacts with each other to form 2 molecules of water. The reaction is 2(g) + (g) = 2(l). Here the origin of the components i.e. hydrogen and oxygen does not matter it depends upon the number of atoms present in the reactant and product. Thus among all the other interpretations- The composition of a substance depends on the total number of atoms and not on the composition of the mixture from which it was formed. This is correct.

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.
