The value lies between 0.4 and 2.00, implying that the bond type is polar covalent. The ammonium ion (see figure below) consists of one nitrogen atom and four hydrogen atoms. If it were, it would a negative charge. Compounds that consist of a nonmetal covalently bonded to a nonmetal are commonly known as Molecular Compounds, where the element with the positive oxidation state is written first. When the distance is increased and the shielding is also increased, it causes a decrease in nuclear attraction.

There is one carbonate ion at a charge of -2. So, when the nucleus does not have that strong of a hold, the electrons tend to drift away, in turn decreasing their capability to attract electrons towards themselves, hence decreasing electronegativity. If the two elements were to form a bond, it would be: Check out 7 similar general chemistry calculators . Ionic Solids. 0.8 Non-Polar Covalent = 0 0 Polar Covalent 2 Ionic (Non-Covalent) 2: Bond Type: Polar Covalent: Bond Length: 1.628 angstroms: Is ClF ionic? Most transition metals form multiple stable cations with different charges, and so you have to identify the charge state, which is done by writing the charge in Roman numerals and placing it in parenthesis after the name of the metal.
