8. Negative Charge

Part 2 - Key Facts:

Ionic Bonding:

• Ionic bonding is a type of chemical bond formed by the transfer of electrons between atoms.

Formation of Ions:

• Atoms lose or gain electrons during ionic bonding, resulting in the formation of ions.

• Cations are positively charged ions formed by losing electrons.

• Anions are negatively charged ions formed by gaining electrons.

Dot and Cross Diagrams:

• Dot and cross diagrams are graphical representations illustrating the transfer of electrons in ionic bonding.

• Dots represent electrons, and crosses represent the absence of electrons.

Part 3 - Quick Quiz:

1. What is ionic bonding?

   b) Transfer of electrons

   c) Mixing of nuclei

   Answer: b) Transfer of electrons

2. What is a cation?

   a) Positively charged ion

   b) Negatively charged ion

   c) Neutral ion

   Answer: a) Positively charged ion

3. How are dot and cross diagrams used in ionic bonding?

   a) To represent atoms' shapes

   b) To illustrate the transfer of electrons

   c) To show the arrangement of nuclei

   Answer: b) To illustrate the transfer of electrons

Part 4 - Going Further:

Question: Explain the process of ionic bonding, focusing on the transfer of electrons and the formation of cations and anions. How do dot and cross diagrams aid in visualising ionic bonding?

Answer: Ionic bonding involves the transfer of electrons, resulting in the formation of cations (positive) and anions (negative). Dot and cross diagrams visually represent this electron transfer, helping to understand how atoms achieve stable electron configurations through ionic bonds.

Part 5 - Revision Tips: Master the concept of ionic bonding, emphasising the role of electron transfer, the formation of ions, and the use of dot and cross diagrams.
