Raiderium (CV) has three naturally occurring isotopes. Raiderium is 74.655% 44 CV, which has an atomic mass of 43.064 amu, 24.958% 46CV, which has a mass
of 46.125 amu, and 0.387% 48Cv, which has an atomic mass of 47.982 amu.
Please calculate the average atomic mass of Raiderium.

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.

a polar bond is formed when electrons are shared unevenly between atoms
