Red 40 ionic or covalent
WebMar 31, 2024 · A nonpolar covalent bond (Figure 4.4. 1 a )is one in which the electrons are shared equally between two atoms. A polar covalent bond (Figure 4.4. 1 b) is one in which one atom has a greater attraction for the electrons than the other atom. If the relative attraction of an atom for electrons is great enough, then the bond is an ionic bond ... WebTextbook Question.

This type of bonding occurs between two atoms of the same element or of elements close to each other in the periodic table. This bonding occurs primarily between nonmetals; however, it can also be observed between nonmetals and metals.
WebMay 7, 2016 · This is explained in a previous question. In the case of A l C l X 3 we have a metal 'cation' and a non-metal 'anion' so in a simplistic view we would expect this to be an ionic compound. However, it actually turns out that the A l − C l bonds display a significant degree of covalent character. In the solid state it adopts an 'ionic lattice ...
