The heat of sublimation for iodine over the range of temperatures from 273 K to 368 K has been reported in the literature: D. A. Shirley and W. F. Giauque, J. Am. Chem. Soc. _81_, 4778-4779 (1959). Table III of that reference contains the information you'll need.
K is potassium and I is Iodine. K is potassium and I is Iodine
Fluorine: 53.48 KBromine: 266 K Chlorine: 171.7 K Iodine: 386.9 K
No. It is two elements: potassium (K) and iodine (I).
Iodine (I) Melting point: 386.85 K, 113.7 °C, 236.66 °F Boiling point: 457.4 K, 184.3 °C, 363.7 °F
Iodine (I) Melting points: 386.85 K, 113.7 °C, 236.66 °F Boiling points: 457.4 K, 184.3 °C, 363.7 °F
There are some covalent compounds that are volatile and undergo sublimation such as iodine. Although, covalent compounds aren't always volatile. For example, diamond, the hardest solid known, does not change its phase even in a higher temperature around 3000 K.
The electronic configuration of iodine is: [Kr] 4d10 5s2 5p5.
The melting point is:- 292 °C, 565 K, 558 °F
Literally, the correct formula for potassium and iodine at standard temperature and pressure would be " K and I2". The formula for the compound formed between potassium and iodine, however, is KI.
457.4 K. note iodine sublimes uunder normal conditions i.e. vaporises without melting
It stands for Kelvin, a measurement of heat.
Specific heat means, how much heat is required to heat a certain mass of something by 1 degree K. For example the specific heat of water is 1 cal/(g*K) (4.184 J/(g*K)).
the heat capacity of iron is 450 J/(kg * K), Heat Conductivity Rates 80 k,
The elements who are ferromagnetic at ambient temperatura (approx. 300 K) are: Iron (TC=1043 K), nickel (TC=627 K), cobalt (TC=1388 K) gadolinium (292 K). (TC = Curie Temperature). and ruthenium
K+ + I- --> KI , potassium iodide
The ion for Potassium has a charge of 1+.The ion for Iodine has a charge of 1-.This means that in order to make the overall charge of a unit of a compound of Potassium and Iodine, there must be one atom of Potassium and one atom of Iodine.Therefore, when K+ and I- are bonded, they make the ionic compound of KI.

You could react : Potassium Metal with Iodine = K+I=KI = Potassium IodideSodium Metal with Iodine = Na+I=NaI = Sodium IodideLithium Metal with Iodine = Li+I=Lii = Lithium IodideFluoridesIodine fluoride: IFIodine trifluoride: IF3Iodine pentafluoride: IF5Iodine heptafluoride: IF7ChloridesIodine chloride: IClDiiodine hexachloride: [ICl3]2OxidesDiiodine pentaoxide: I2O5Diiodine tetraoxide: I2O4Tetraiodine nonaoxide: I4O9
you mean phosphorus (P). potassium has a symbol K
Iodine was discovered by the French chemist Barnard Courtois in 1811. Iodine is a bluish-black, shiny solid. Although it is less reactive than the elements above it in group 17 (fluorine, chlorine and bromine) it still forms compounds with many other elements. Iodine is a non-metal. It's boiling point is 457 K (184 oC) and melting point is 386.6 K (113.5 oC). Iodine belongs to group 7A ,the Halogens. Belongs to period 5 in the Periodic table. Iodine might be used in its pure form, but most of the times it is not used as a pure iodine.
(350/300)*250 mL = 292 mL
Iodine is indispensable for the health; iodine is added to table salt as K(or Na) iodides or iodates.
