H2SO4 is also called
a. king of acid
b. king of chemical
c. blue vitriol
d. Antacid

Explanation:

H2SO4 (also called sulfuric acid) is also called King of Acids. It is a highly reactive acid.

Explanation:

or sulfuric acid is known as the king of acid. It is a very reactive acid and is a strong acid in general.

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.
