Ethane (C2H6) has one C-C bond and six C-H bonds. The electronegativity difference between carbon and hydrogen is less than 0.4. What is a property of ethane?

Ethane is nonpolar because it has an uneven distribution of charge across the entire molecule, which results from the large electronegativity difference between the carbon and hydrogen atoms.

Ethane is nonpolar because it has an even distribution of charge across the entire molecule, which results from the small electronegativity difference between the carbon and hydrogen atoms.

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.

its first and third is your answer i did the qustion the fourth isnt right

all eukaryotic cell have mitochondria : )
