The diagram below models the relative sizes of particles found in an atom. x y not to scale Which list correctly identifies each particle? x represents an electron, and y represents a proton and neutron. x represents a proton, and y represents a neutron and electron. x represents an electron and neutron, and y represents a proton. x represents a neutron, and y represents an electron and proton.

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.

dynamic equilibrium is the answer.
