answer:

largest planet is jupitor

explanation:

answer:

the biggest planet is jupiter.

explanation:

astronomers have crowned the universe's largest known spiral galaxy, a spectacular behemoth five times bigger than our own milky way. the title-holder is now ngc 6872, a barred spiral found 212 million light-years away in the southern constellation pavo, researchers announced today

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.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
