Ionic bonding
Ionic bonding is a fundamental concept in chemistry, involving the transfer of electrons between metals and non-metals to form charged ions. This process results in the creation of ionic compounds, held together by strong electrostatic forces. Metal ion electron shell configurations play a crucial role in determining the type and strength of ionic bonds formed.

Metals and non-metals form ions differently, which is crucial for understanding ionic bonding:
Metals always lose electrons to become positive ions. This process involves the removal of electrons from the outermost shell, resulting in a smaller ion with a positive charge.
Example: Lithium (Li) loses one electron to become Li+, while aluminum (Al) loses three electrons to become Al3+.
Non-metals, on the other hand, always gain electrons to become negative ions. This process involves the addition of electrons to the outermost shell, resulting in a larger ion with a negative charge.
Example: Nitrogen (N) gains three electrons to become N3-, while oxygen (O) gains two electrons to become O2-.
The electron configuration of these ions is important:
Vocabulary: The electron configuration refers to the arrangement of electrons in an atom or ion.
For example:
Understanding these electron configurations is essential for predicting and explaining ionic bonding behavior.
Ionic bonding occurs in compounds composed of a metal and a non-metal. Two important examples of ionic compounds are ionic bonding sodium chloride and calcium chloride ionic compound.
In the formation of sodium chloride:
Highlight: The resulting sodium ion has a +1 charge, while the chloride ion has a -1 charge.
The electron configurations change as follows:
The ionic bond forms due to the electrostatic attraction between these oppositely charged ions.
Calcium chloride formation involves:
Vocabulary: When a non-metal element forms an ion in a compound, its name often changes. For example, chlorine becomes chloride in calcium chloride.
The electron configurations change as follows:
Highlight: In calcium chloride, one calcium ion bonds with two chloride ions to maintain electrical neutrality.
Understanding these bonding processes is crucial for comprehending the structure and properties of ionic compounds.
Ionic bonding is not limited to simple binary compounds. Let's explore another example: sodium oxide (Na₂O).
In the formation of sodium oxide:
Example: The formation of sodium oxide can be represented as: 2Na + O → Na₂O
The electron transfer process:
Highlight: The resulting compound has two sodium ions for every oxide ion to maintain electrical neutrality.
This example demonstrates how the principles of ionic bonding apply to more complex compounds, where the ratio of cations to anions may not be 1:1.
Understanding these various examples of ionic bonding helps in predicting the formulas and properties of a wide range of ionic compounds, which is essential in many areas of chemistry and materials science.

Ionic bonding is a key concept in chemistry, involving the transfer of electrons between metals and non-metals. This process results in the formation of positively and negatively charged ions, which are then held together by strong electrostatic forces.
Definition: Ionic bonding is the electrostatic attraction between oppositely charged ions.
The formation of ions depends on the electron configuration of atoms:
Example: In the formation of ionic bonding sodium chloride, sodium loses one electron to become a Na+ ion, while chlorine gains one electron to become a Cl- ion.
The number of electrons lost or gained depends on the element's group number in the periodic table:
Highlight: The goal of ion formation is for atoms to achieve a full outer shell of electrons, which provides stability.
