Is NaI ionic or polar covalent?
Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a white, water-soluble solid comprising a 1:1 mix of sodium cations (Na+) and iodide anions (I−) in a crystal lattice.
Is NaI nonpolar or polar?
NaI is an ionic compound which can dissolve in water due to the polar nature of water molecules. [example here]. Iodine is made up of molecules of I2, which individually have no dipole moment (I-I bond has no dipole as both iodine atoms have same electronegativity).
Does NaI have ionic bond?
An ionic bond would form, as Na becomes Na+ and Cl becomes Cl-. They are now stuck together as ions in a compound NaCl. But now consider NaI, which definitely does have ionic bonds. Iodine has an electronegativity of 2.5 compared to Na at 0.9, for a difference of 1.6.
How do you tell if a bond is polar or nonpolar or ionic?
If the difference of the electronegativity between the two elements is greater than 1.7 then the bond is ionic. The difference with a polar covalent bond is 0.5 to 1.7 and a nonpolar covalent bond is from 0 to 0.4.
Is NaI metal or nonmetal?
A binary ionic compound is composed of ions of two different elements - one of which is a metal, and the other a nonmetal. For example, sodium iodide, NaI, is composed of sodium ions, Na+ (elemental sodium is a metal), and iodide ions, I- (elemental iodine is a nonmetal).
Is caco3 ionic or covalent?
Calcium carbonate (CaCO3) has ionic bonding between calcium ion Ca2+ and a polyatomic ion, CO2−3, but within the carbonate ion (CO32-), the carbon and oxygen atoms are connected by covalent bonds (shown above).
Why is NaI a covalent bond?
NaI is the most covalent due to small size of cation and large size of anion. Explanation: Covalent bonds are defined as the bonds which exists due to sharing of electrons between the combining atoms.
Does NaI contain a covalent bond?
For example, in NaI, the sodium is present as sodium ions and the iodine as iodide ions. ... In covalent compounds there are no charged ions; the atoms are held together by covalent bonds. These covalent bonds are believed to be a result of the sharing of electron density between two atoms.
Is SiO2 ionic or covalent?
SiO2 has COVALENT bonds. A double bond to each of the two oxygen atoms. Also known as silica, quartz and others.
What are non-polar bonds?
A bond between two atoms or more atoms is non-polar if the atoms have the same electronegativity or a difference in electronegativities that is less than 0.4. An example of a non-polar bond is the bond in chlorine.
Which of the following is non-polar molecule?
Any of the homonuclear diatomic elements: H2, N2, O2, Cl2 (These are truly nonpolar molecules.) Carbon dioxide - CO. Benzene - C6H. Carbon tetrachloride - CCl.
