ANSWER
•potassium=
1)Potassium is a silvery-white,
2)very soft metal that is quickly oxidized in air and rather violently oxidized in water.
3) Its relatively low atomic number (16) makes it fairly common, though pure metallic potassium is relatively rare and not organically available.
N.B.
Most potassium on earth is found in the form of ionic salts, which are common in seawater.
•ioidne=
1)Iodine is a halogen
2)its high atomic number=(53) ,makes it a relatively rare element.
•potasium iodide(KI)=
1)Potassium iodide (KI) is also known iodine-127.
2)It is extremely biologically active.
3) It is used in case of nuclear exposure.
