they look like small circles which float around
magenta vapout
Violet - blue I2 molecules
they are all over the place. e.g. scattered.
You can not see Gas!!!!!Though there are some gases with colour to see: this one is violet - blue I2
At the molecular level iodine gas contains I2 molecules, which if you could see them ( they are too small to be seen using light) and you were able to see the electron density then they would appear as small dumbells. When iodine sublimes the colour of the "gas" is violet this due to the aborption of visible light by the I2 molecule.
When combined with other substances, iodine particles can change through chemical reactions, forming new compounds or mixtures. The arrangement of iodine particles may also change depending on the nature of the interaction, such as forming ionic or covalent bonds with other elements. In some cases, the physical state of iodine (solid, liquid, or gas) can shift, affecting how the particles are organized. Overall, both the particles and their arrangement can change when iodine interacts with other substances.
It is called sublimation
Iodine gas is usually described as having an "irritating" odor.
they both sublime, in which the solid particles will change directly into gas.
it's called sublimation
When iodine is heated, it sublimes directly from a solid to a purple gas. The gas produced is diatomic iodine molecules (I2).
The purple gas formed when heating solid iodine in a test tube is iodine vapor. Iodine sublimes directly from a solid to a gas when heated, turning into a purple gas that condenses back into solid iodine crystals when cooled.
