What halogen is violet?
Iodine is a halogen that can appear violet in its elemental form or as certain compounds.
What element is in a violet gas form?
The element present in a violet gas form is iodine. When iodine is heated, it sublimes directly from a solid to a gas, producing a distinctive violet vapor.
What happens when a solid sublimes?
When ice sublimes, the molecules at the edge of the ice escape into the gas phase as water vapor. The solid phase thus turns directly into the gas phase without an intermediary liquid phase. Ice sublimes quite slowly under normal conditions, but dry ice (solid carbon dioxide) sublimes readily at everyday temperatures and pressures.
What are two properties which the halogen vapors have in common?
Halogen vapors are highly reactive due to their ability to gain electrons, making them strong oxidizing agents. They also have distinct colors, ranging from yellow (for chlorine) to orange (for bromine) to purple (for iodine).
What are the names of the three states of iodine?
The three states of iodine are solid, liquid, and gas. At room temperature, iodine is a solid with a dark purple color. When heated, it sublimes directly from a solid to a purple-violet gas.
What halogen is violet?

What vapor colors does iodine have?
violet vapours
Which halogen goes from the solid phase directly to a gas?
Iodine is the halogen that sublimes directly from a solid to a gas at standard pressure and temperature.
What element is in a violet gas form?
The element present in a violet gas form is iodine. When iodine is heated, it sublimes directly from a solid to a gas, producing a distinctive violet vapor.
What is a dark grey solid that sublimes to form a violet vapor?
Iodine ( I2 ) the fourth halogen (after F2 ,Cl2 -both gases- and Br2 -liquid- ) Iodine has a shiny, dark grey, metallic look (but it is not a metal) with crystal forms which subliMATES to violet vapour. It is slightly soluble in water, better in a Iodide solution (to form I3- complex ions) and in ethanol (red-brown tincture)
A substance that exists as a solid at ordinary temperature but changes to vapour on heating?
Substance that changes directly from a solid to a gas without passing through the liquid state is known as sublimation. An example of a substance that exhibits this property is dry ice (solid carbon dioxide), which sublimes at -78.5 degrees Celsius.
Does solid iodine give blue gas on sublimation?
Yes, solid iodine sublimes directly to a purple vapor, not blue.

What state of matter is iodine at room temperature?
At room temperature iodine is a solid halogen.
Why NH4CL crystals have this tendency to creep up against the glass wall?
ammonium chloride sublimes slowly at room temperature. As the vapours come in contact with the surface, the condense back to solid state. And it appears as if the solids has creeped up the glass wall

What are vapours?
water vapours are particles of water when water is boiled at a certain temperature the smoke you get is water vapours
