Which of the following will be most covalent NaCl NA _( 2 S MgCl _( 2 MGS?

The size of magnesium (Mg) is lesser than sodium(Na). Covalent characteristics will be more if the size of the cation is small. Therefore, MgCl2 is more covalent than NaCl.

Which ionic compound is more covalent?

Cl-F. Cl has an electronegativity of 3.16. F-F is the most covalent because the electronegativity values are the same so the difference would be zero.

Which is more covalent be or Mg?

Be is above Mg in group 2 of the periodic table. Since in the same group, ionisation energy decreases with increasing size of the atom. Since Be atom is smaller than Mg atom, the statement that BeO is more covalent because of smaller size of Be is also correct.

Why lattice energy of MgCl2 is greater than NaCl?

The lattice enthalpy of magnesium oxide is also increased relative to sodium chloride because magnesium ions are smaller than sodium ions, and oxide ions are smaller than chloride ions. That means that the ions are closer together in the lattice, and that increases the strength of the attractions.

Which is more ionic NaCl or MgO?

In MgO, the ionic bond is stronger than in NaClbecause of more charge on the ionicspecies in the former (Mg+2 and O2- as compared to Na+ and Cl-). Because of this the ionic interactions are stronger in MgO than in NaCl.So MgO is more ionic than NaCl.

Which is more covalent be or MG?

Which is more covalent NaCl or NaF?

covalent characters of halides of sodium increases in order NaF < NaCl < NaBr < NaI . This is because the ionic radii of the halide anions increase on moving down the group. Hence, the polarisability of the iodide ions is maximum. This is followed by the bromide, chloride and lastly by the fluoride ions.

Is Na and O ionic or covalent?

Na2O is an ionic compound because the bond formed between sodium and the oxygen atom is ionic in nature, it is formed as each sodium atom loses one electron to form Na+ ion and oxygen atom accepts these electrons to form O2– ion, later these ions(2Na+ and O2-) are attracted by the electrostatic force of attraction and …

Is Na and F ionic or covalent?

One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom. In this reaction, the sodium atom loses its single valence electron to the fluorine atom, which has just enough space to accept it.
