In a ball-and-stick molecular model, what do the sticks represent?

Explanation:

A molecular model that consists of balls in the shape of spheres and sticks is known as a ball-and-stick model.

In this type of model, spherical balls represent the atoms present in the model whereas sticks represents the bonds present between combining atoms.

According to the standard molecular art, different colors of represent specific atoms. For example, black represents carbon atom, white represents hydrogen atom, blue represents nitrogen etc.

Thus, we can conclude that in a ball-and-stick molecular model, sticks represent bonds.

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.
