The state of matter of a material depends on its O A) density
OB) temperature
O C) volume
OD) weight

Tempature

Explanation:

Matter can move between any two states (or phases) of matter depending on the pressure and temperature conditions. ... The temperature of the melting and boiling points depend on the identity of the substance and the atmospheric pressure.

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 a and have a great day
