Is an ion the same as a compound?
The atoms in chemical compounds are held together by attractive electrostatic interactions known as chemical bonds. Ionic compounds contain positively and negatively charged ions in a ratio that results in an overall charge of zero. The ions are held together in a regular spatial arrangement by electrostatic forces.
Are ions compounds or atoms?
A molecule is a neutral particle, composed of a set number of atoms bonded together. The particle of the substance is the molecule, rather than the atoms that make up the molecule. By contrast, ionic compounds are made up of an indeterminate number of ions, in a fixed ratio.
What makes a compound ion?
Ionic compounds are the attraction between positively and negatively charged ions. Ions are formed when atoms gain or lose electrons or combinations of elements bonding sharing electrons result in the unit having an electric charge.
Can a compound be classified as ionic?
Not always. But there is a rule of thumb that makes it easy to recognize many compounds as ionic. Compounds that contain both metals and nonmetals are usually ionic. For example, Na2SO4 contains a metal (Na) and nonmetals (sulfur and oxygen), and so is expected to be ionic.
Are compounds molecules?
A molecule is a group of two or more atoms held together by chemical bonds. A compound is a substance which is formed by two or more different types of elements which are united chemically in a fixed proportion. All molecules are not compounds. All compounds are molecules.
What substances are ionic?
What are Ionic Compounds?
- sodium chloride: NaCl, with Na+ and Cl- ions.
- lithium nitride: Li3N, with Li+ and N3- ions.
- magnesium oxide: MgO, with Mg2+ and O2- ions.
- calcium phosphide: Ca3P2, with Ca2+ and P3- ions.
How do you classify ions?
The nomenclature for binary ionic compounds simply entails naming the ions according to the following rules:
- The positive ion (called a cation) is named first and the negative ion (anion) second.
- A simple cation (obtained from a single atom) takes its name from its parent element.
What do you know about ionic compounds?
Ionic compounds are compounds made up of ions that form charged particles when an atom (or group of atoms) gains or loses electrons. A cation is an ion charged positively; an anion is an ion charged negatively.

How are the cations and anions arranged in an ionic compound?
In an ionic compound, the cations and anions are arranged in space to form an extended three-dimensional array that maximizes the number of attractive electrostatic interactions and minimizes the number of repulsive electrostatic interactions ( Figure 2.7. 1 ).
Are ionic compounds with hydrogen ions acids or bases?
Ionic compounds containing hydrogen ions (H +) are classified as acids, and those containing basic ions hydroxide (OH −) or oxide (O 2−) are classified as bases. Ionic compounds without these ions are also known as salts and can be formed by acid–base reactions.
How do you find the number of ions in a compound?
All you have to do to determine how many of each ion will be in the compound is take a quick look at the periodic table. Let’s start with our table salt, the sodium chloride. Sodium is in the first column of the periodic table, so it will lose one electron. Chlorine is in the second-to-last column, so it will gain one electron.
