How does the author describe the healing power of micronutrient supplements?

Micronutrients includes, Mn, Fe, Zn, Cu , Ni, etc which helps the skin to protect it from various damages also helps in maintaining skin’s health.

Micronutrients helps in preventing the skin from different types of allergens or pollen which may result in skin rashes or hives.

It protects skin againts various pathogens or fungi.

It acts as anti oxidants on skin and thus prevents premature ageing.

It also protects from harmful UV radiateion which damages DNA.

Thus,  Micronutrients helps in maintaining skin’s health

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.
