------
Hydrogen fluoride has a Polar-covalent bond although, while the difference in electronegativity is more than 1.7 ( we expected to be Ionic ).
Rubidium by itself is neither ionic nor covalent. When it forms bonds with other elements, it forms ionic bonds.
Covalent, the difference in electronegativity of 2.0 and fluoride of 4.0 is borderline for covalent and ionic, the bond will be polar.
In pure hydrogen fluoride, each bond is a highly polar covalent bond.
NH3 is eventually covalent because they are sharing electrons.
Ammonium Fluoride is polar.

if ∆EN < 0.5, the substances is non polar covalent if 0.5 < ∆EN < 1.5 the substance is polar covalent. if 1.5 < ∆EN < 2.0 and it contains a metal, it is ionic, otherwise it is polar covalent if 2.0 < ∆EN then the substance is ionic CaF2 (calcium fluoride) has a ∆EN of 2.98.. so, it is definitely ionic Cancel
Yes...hydrogen fluoride (HF) has polar covalent bonds
There are two types of bonding in ammonium sulphate. In ammonium ion, ntrogen and hydrogen are bonded by covalent bonds (intermolecular / Van Der Waals forces) as both of the elements are non-metals. Between ammonium and sulphate, both ions, they are joined together by ionic bonds.
Polar Covalent
it is ionic, soluble in polar solutes the reason it will not dissolve in water is dure to the nature of fluorides not wanting to let go of their cations
Ammonium ion is polar due to the ionic bonds present in the polyatomic ion.
