Ammonia is made up of nitrogen and hydrogen. Nitrogen is in Group 15 of the periodic table, and hydrogen is in Group 1. Which statement about the bonds in a molecule of ammonia is correct? Each nitrogen atom is bonded to two hydrogen atoms.

Each hydrogen atom is bonded to two nitrogen atoms.

Each nitrogen atom is bonded to three hydrogen atoms.

Each hydrogen atom is bonded to three nitrogen 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.

1 is the answer to this problem

the correct answer would be b) volume versus temperature, because they are also directly proportional.
