What will happen if we combine the solution of sodium iodide and the solution of lead(ii) nitrate? the solutions will mix, so all of the ions will be evenly distributed throughout the entire solution. but sometimes mixing solutions containing dissolved ions leads to a precipitation reaction: the formation of a new insoluble compound. based on the information presented in that table, complete the balanced overall ionic equation for the mixing of these two solutions.
2na+(aq) + 2i-(aq) + pb+2(aq) + 2no3-(aq)

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.
