Question

what is the difference between 3Cl and 4Cl2​

Answer 1

The difference between 3Cl2 and 4Cl2 is In 3Cl2 there are 2 molecules of chlorine and in 4Cl there are 4 molecules of chlorine.

Answer 2

Answer:

$3$Cl is a 3chlorine atom and $4$$Cl_{2}$ is$4$  chlorine molecule

Explanation:

Two atoms make up a chlorine molecule$Cl_{2}$ Except for the lighter noble gases, chlorine reacts with practically all other elements to form chlorides; those of most metals are ionic crystals, while those of semimetals and nonmetals are mostly molecular. It has a yellow-green colour and a smell that is comparable to that of home bleach. It is water-soluble and interacts with water to create hypochlorous and hydrochloric acids.

Chlorine is a$17$-proton atom with either $18$ or $20$ neutrons in its nucleus, as well as $17$ electrons, revolving around it. Chlorine is found in compounds due to its strong reactivity. Although free chlorine is uncommon, it does occur as a thick, diatomic gas. Chlorine is a greenish-yellow gas or liquid with a pungent odour.
