What is the formula for Na and I?
Formula and structure: The chemical formula of sodium iodide is NaI and its molar mass is 149.89 g/mol. It is a simple ionic compound composed of the sodium cation (Na+) and iodide anion (I-), and its chemical structure is shown below.
Why is Na Na+?
Opposite charges attract each other (positive charge attracts negative charge, and vice versa), so a collection of cations and anions is stable. Neutral sodium atom (Na) becomes sodium cation (Na+) by releasing an electron.
Why is potassium iodide ionic?
Metals react with nonmetals to form ionic compounds. A sodium atom transfers an electron to a chlorine atom to form a sodium ion and a chloride ion. In the same way, a potassium atom transfers an electron to an iodine atom to form a potassium ion and an iodide ion. So, potassium iodide is an ionic compound.
What Colour is iodide ion?
colourless
Although the iodide ion is colourless, iodide solutions may acquire a brownish tint as a result of oxidation of iodide to free iodine by atmospheric oxygen.
