How is it possible to predict the type of bond that is likely to be found in a substance? what types of atoms generally form ion
Alenkasestr [34]
Using electronegativity difference is a good guide to the ionic/ covalent nature. Large differences indicate greater ionic character, small differences more covalent character. The larger the difference in electronegativity the more ionic properties a bond is said to have. The smaller the difference in electronegativity the more covalent properties a bond is said to have. 
Ionic bonding is formed through electrostatic attraction between a cation and anion. Foe example, Sodium fluoride has ionic bonding because it is composed by sodium and Fluorine (a non metal). On the other hand, covalent bonding is characterized by atoms sharing pairs of electrons. For example; methane has covalent bonding; carbon has 4 valence electrons and hydrogen has 1; when they bond they have a total of 8 electrons and satisfies the octet rule.

When is a Roman numeral most likely needed in the name of an ionic compound
Inessa [10]

Answer:

When the metal of the ionic compound has multiple oxidation states.

Explanation:

Nickel (Ni - At No 28) has multiple oxidation states* => −2, −1, 0, +1,[2] +2, +3, +4[3] (a mildly basic oxide)*. When naming compound of nickel on needs to include a roman numeral in parenthesis after the symbol of the element in order to identify which oxidation state is relevant.

examples

Nickel Halide derivatives include

NiCl => nickel(I) chloride

NiCl₂ => nickel(II) chloride

NiCl₃ => nickel (III) chloride

Such is important in that each of the compounds have different physical and chemical properties due to variations in oxidation states of nickel.
