Why is NaCl stronger than NaI?
The ionic bond strength varies between two. Since Chlorine is smaller, hence the distance between the ions is overall smaller in the crystal structure the ionic bond of NaCl is stronger than NaI and this is reflected by NaCl having an higher melting point.
Which compound would have a stronger ionic bond NaCl nal?
The ionic bonding is stronger than in sodium chloride because this time you have 2+ ions attracting 2- ions. The greater the charge, the greater the attraction. The formula of magnesium oxide is MgO. This time you need two chlorines to use up the two outer electrons in the calcium.
Is NaCl or nah more ionic?
NaCl is more ionic than NaI.
Which compound would have a stronger ionic bond?
A cation with a 2+ charge will make a stronger ionic bond than a cation with a 1+ charge. A larger ion makes a weaker ionic bond because of the greater distance between its electrons and the nucleus of the oppositely charged ion.
Why NaI is 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.
Is NaCl or NaI more conductive?
Figure 11.2. 1: The conductivity of electrolyte solutions: (a) 0.1 M NaCl (b) 0.05 M NaCl (c) 0.1 M HgCl2. An electrolyte solution conducts electricity because of the movement of ions in the solution (see above)….Electrolytes.

Is NaI ionic or covalent?
Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine.
Which chemical bond is the strongest?
Covalent bonds
Covalent bonds are the strongest (*see note below) and most common form of chemical bond in living organisms. The hydrogen and oxygen atoms that combine to form water molecules are bound together by strong covalent bonds.
Why is ionic bond stronger than covalent bond?
As we shall explore in this section on ionic bonding, ionic bonds result from the mutual attraction between oppositely charged ions. They tend to be stronger than covalent bonds due to the coulombic attraction between ions of opposite charges.
Why BeO has higher melting point than NaCl?
BeO has higher melting point than NaCl because of stronger force of attraction between atoms. Explanation: Because BeO atom share two electrons and form double bond, and NaCl form only a single bond, hence it requires little energy to break down then BeO.
