Chromium chloride can is either CrCl3 or CrCl6. A salt is usually uncharged since the cation (here Cr3+ or Cr6+) and the anion (Cl-) combine to neutralise the charges and form a salt. Some salts can have some covalent characteristics though, but in this case both compounds above are neutral.
Chromium (III) nitrate is formed by the reaction between Cr3+ ions and NO3- ions. Thus, forces of attraction due to disparity of charges causes this reaction. As such, we can safely say this is an ionic compound because it is formed by ions.
Ionic, because chromium is a metal and chlorine is a non-metal.
Ionic - Chromium is a metal and Oxygen is a non-metal.
Both. The anion Cr2O72- is an example of covalency.
The mmon ions of chromium are Cr3+ and Cr6+; also exist valences 0, 1, 2, 4 and 5.
Chromium is 3+.
Yes, the bond is covalent.
2 +ve
Ionic.
Ionic bond
No, Ionic
NH4 + and F - Form the ionic bond, NH4F ------
In pure hydrogen fluoride, each bond is a highly polar covalent bond.
Chromium oxide (Cr2O3) is an ionic compound, since it is made up of a metal and a nonmetal.
Ionic bond
No, Ionic
Barium fluoride is a compound, not a bond. It has ionic bonding.
NH4 + and F - Form the ionic bond, NH4F ------
In pure hydrogen fluoride, each bond is a highly polar covalent bond.
An ionic bond is where electrons are transferred from one to the other, but a covalent bond is where the electrons are 'shared'.
Chromium oxide (Cr2O3) is an ionic compound, since it is made up of a metal and a nonmetal.
Ca is a metal. F is a non metal. The bond between a metal and non metal is considered an ionic bond.
Covalent, the difference in electronegativity of 2.0 and fluoride of 4.0 is borderline for covalent and ionic, the bond will be polar.
It forms the fluoride by forming an ionic or covalent bond with the element.Example:-HF(hydrogen fluoride) which if an ionic compound.OF2(Oxygen difluoride) which is a covalent compound
Hydrogen fluoride has a Polar-covalent bond although, while the difference in electronegativity is more than 1.7 ( we expected to be Ionic ).
Calcium and fluorine will form an ionic bond.
