Which among the two is more ionic NaCl or NaI and why?

NaCl is more ionic than NaI because chlorine is more electronegative than iodine.

Which is more ionic NaCl or NaBr?

The decreasing order of ionic character NaF>NaCl>NaBr>NaI N a F > N a C l > N a B r > N a I . Because among the halogens the electronegativity is more for Fluorine followed by Chlorine, Bromine, Dodine. According to Fajan’s rule, the size should be small to have more ionic character. Thus NaF N a F is more ionic.

Which is more ionic NaF or NaI?

Now, among halogens i.e. chlorine, fluorine, bromine and iodine, fluorine has the highest electronegativity and hence it is considered as the most ionic followed by chlorine and bromine. Hence, NaF is more ionic.

Why is NaI ionic?

In ionic compounds, the atoms are present as ions; that is, as charged particles. For example, in NaI, the sodium is present as sodium ions and the iodine as iodide ions. These covalent bonds are believed to be a result of the sharing of electron density between two atoms.

Is NaCl more ionic or covalent than Nai?

So it will attract electron from sodium atom and convert it in sodium ion to large extent which will develop a covalent character in it. Moreover electronegativity difference in NaI is 0.6 which means it is more covalent and in NaCl it is 2.1 which means it is more ionic. 1k views · View 2 Upvoters.

Why is sodium chloride more ionic than silver chloride?

Since the sodium is in period 3, and group 1a it is more electronegative than silver is. That means the bond character of Sodium Chloride will be more ionic. The bond character of Silver chloride is less ionic. The more ionic in character a bond is, the less covalent it will be.

Which is more ionic nai or nanaf?

NaF is more ionic than NaI. In both these two ionic compounds the cation is common (Na+).

Why does chlorine become a covalent compound when it reacts with sodium?

Electron gain enthalpy of chlorine is most negative so it has more tendency to gain electron. So it will attract electron from sodium atom and convert it in sodium ion to large extent which will develop a covalent character in it.
