The kinetic molecular theory states that all particles of matter are a. in the form of a gas. b. always in motion. c. very close together. d. compressible. (not a or c)

Option (B) is the correct answer.

Explanation:

Kinetic molecular theory states that all the particles present in a matter constantly move from one place to another.

This is because all particles have certain energy but this energy changes with change in temperature. The amount of energy will help in determining whether the matter is in solid, liquid or gaseous phase.

Therefore, by changing the temperature, a change in phase will occur.

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.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
