之间的区别Iodine and Potassium Iodide

这关键区别between iodine and potassium iodide is thatiodine is a chemical element whereas potassium iodide is a chemical compound.

碘是halogenthat locates in group 17 of元素周期表。On the other hand, potassium iodide is a chemical compound that forms from the combination of iodine and potassium. As a result, potassium iodide is very useful in many industries as a source of iodine.

什么是碘？

碘是具有原子数53和化学符号的化学元件。它是其他卤素中最重的卤素。卤素是元素周期表中的17组化学元素。此外，碘作为一种有光泽的金属灰色在室温下存在。但是，它很容易发生sublimationto form the violet gas of iodine. Moreover, among the oxidation states that iodine can exist, the -1 oxidation is the most common among them, which results in the iodide anion. It is because, the iodine has an incomplete八位字在其电子构型中，它需要电子才能完成八位位组。然后，当它从外部获得电子时，它会形成-1氧化态。

Some important facts about iodine are as follows:

• 原子数 - 53
• Standard atomic weight – 126.9
• Appearance – lustrous, metallic-grey solid
• 电子配置 - [KR] 4D¹⁰5s²5p⁵
• 小组 - 17
• Period – 5
• Chemical category – nonmetal
• Melting point is 113.7 °C
• 沸点为184.3°C

Moreover, iodine is a strong oxidizer. Mainly, it is due to its incomplete octet of electron configuration in which it lacks one electron to fill up the outermost p orbital. Thus, it seeks for an electron by oxidizing other chemical species. However, it is the weakest oxidizing agent among other halogens due to its large atomic size.

什么是碘化钾？

碘化钾是一种无机化合物，看起来像白色固体，并在商业上大量生产。它是最重要的碘化物化合物，因为它比任何其他碘化物化合物的吸湿性较小。该化合物的化学配方是Ki。

有关该化合物的一些重要化学事实如下：

• Chemical formula – KI
• 摩尔质量 - 166 g/mol。
• 熔点为681°C。
• Boiling point is 1,330 °C.
• 它具有氯化钠的晶体结构。
• 温和的还原剂。
• Production is industrially by treating KOH with iodine.

KI最重要的应用是在m of SSKI (saturated solution of potassium iodide also) tablets. These tablets are taken in the emergency treatment of several ailments. Also, SSKI is useful for the treatment in the cases of exposure to nuclear accidents. Furthermore, KI is a supplement for iodine deficiency when added to table salt. Moreover, we can use it in the photography industry and in the field of biomedical research.

碘和碘化钾有什么区别？

碘是一种化学元件，具有原子数为53和化学符号I，而碘化钾是一种无机化合物，看起来为白色固体，并大量商业生产。因此，碘和碘化钾之间的关键区别在于碘是化学元素，而碘化钾是化合物。简而言之，碘与钾（例如KOH）结合起来产生碘化钾化合物。作为碘和碘化钾之间的另一个重要区别，我们可以说碘具有有光泽的金属灰色外观，而碘化钾则作为白色固体化合物。

Furthermore, there is a difference between iodine and potassium iodide in their usage as well. Also, there are few other differences in their chemical properties too. The below infographic summarizes the difference between iodine and potassium iodide in tabular form.

Summary – Iodine vs Potassium Iodide

碘为卤素不能在标准温度和压力下作为元素保留，但与其他元素结合起来，可以轻松形成化合物。因此，形成化合物的正是这种属性使其成为非常重要的元素。因此，碘和碘化钾之间的关键区别在于碘是化学元素，而碘化钾是化合物。碘与钾相结合，形成碘化钾，这是一种非常重要的化合物，在各种行业都有商业有用。但是，碘同位素对人类是危险的，但是当这种碘以Ki的形式服用时，它对人类变得有用。此外，碘缺乏会导致智力低下和巨人，这种缺乏症可以通过Ki的形式来实现碘。
