The chemical formula of salt is NaCl. A salt packet from McDonald's contains 0.5 grams of sugar. A salt crystal from on of those fancy salt
grinder things has mass of 0.75g. How many MORE molecules of salt are
in a salt crystal compared to the McDonald's salt packet? EXPLAIN how
you got to your answer including the math you would do. *

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.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
