Is a compound ionic or covalent?
Partial ionic and covalent character. It is possible to have interatomic bonds that are partially ionic and partially covalent, and, in fact, very few compounds exhibit pure ionic or covalent bonding. For a compound, the degree of either bond type depends on the difference in their electronegativities.
How do ionic bonds work?
In an ionic bond, one atom essentially donates an electron to stabilize the other atom. In other words, the electron spends most of its time close to the bonded atom . Atoms that participate in an ionic bond have different electronegativity values from each other. A polar bond is formed by the attraction between oppositely-charged ions.

What are the two types of bonds that make up a compound?
A molecule or compound is made when two or more atoms form a chemical bond, linking them together. The two types of bonds are ionic bonds and covalent bonds. The distinction between them has to do with how equally the atoms participating in the bond share their electrons.
Is a covalent bond nonpolar?
In a true covalent bond, the electronegativity values are the same (e.g., H 2, O 3 ), although in practice the electronegativity values just need to be close. If the electron is shared equally between the atoms forming a covalent bond, then the bond is said to be nonpolar.
What is binary ionic compound?
Binary ionic compounds - As the name suggests, these are formed from two different elements, a metal and a non-metal. There may also be more than one of each element in the compound. It's not to be confused with a diatomic compound, which has multiple atoms of the same element.

Why don't solid ionic compounds conduct electricity?
Conductivity - Solid ionic compounds don't conduct electricity because the movement of ions is impossible. They are good conductors in a molten state and solutions.
How do atoms become ions?
In other words, atoms become ions by losing or gaining electrons. You might have heard the terms cation and anion. Well, they're simply two different types of ions. What is the difference between a cation and an anion, then? Cations have more protons than electrons, meaning that their charge is positive. Funnily enough, the type of electrode they're attracted to is called a cathode despite being negatively charged. Anions are the opposite as they have a negative charge and are attracted to anodes.
What is the simplest organic compound?
Hydrocarbons - A type of covalent compound, these are the simplest kind of organic compounds as they're composed of only hydrogen and carbon. If you've ever heard of alkenes, they fall under this category.
What does the Roman numeral in a chemical name indicate?
You may wonder "What does the Roman numeral in a chemical name indicate, then?" and be completely justified. Generally, these refer to the oxidation number of an atom but it's a bit different for ionic compounds. Some cations, usually transition metals, can take on multiple charges and we want to specify which ion we are considering. This is done by writing the Roman numeral in parentheses following the element name. For example, MnBr₂ is manganese (II) bromide - Mn has a charge of 2+. MnBr₃ would be called manganese (III) bromide as the charge is different.
What happens when two atoms have a large difference in electronegativities?
If two atoms have a large difference in electronegativites, a large amount of energy will be released upon forming the bond. If two atoms have a small difference in electronegativities, the energy released on formation of the bond will be small. Click here for a more detailed description of Electronegativity.
What is the ability of an atom within a molecule to pull electrons away from a binding partner?
Electronegativity is the ability of an atom within a molecule to pull electrons away from a binding partner (another atom in the molecule). If the difference is > 2.0, the bond is ionic. For example, NaCl is an ionic bond, as Sodium (Na) has “given” its electron to Chlorine (Cl).
