The file discusses dot-and-cross diagrams, specifically focusing on how atoms follow the expanded octet rule and the incomplete octet rule in covalent compounds. It also touches on the concept of ionic compounds and how atoms transfer their outer/valence electrons. The diagrams illustrate how atoms ...

The content discusses the shapes of molecules based on the Valence Shell Electron Pair Repulsion (VSEPR) theory. According to VSEPR, electron pairs repel each other, leading to specific molecular shapes that minimize these repulsive forces. The theory emphasizes that different types of electron pair...

Metallic bonding involves metal atoms arranged in tightly packed lattice structures, where the outer shell electrons are free to move. These free-moving electrons, known as delocalised electrons, are not bound to any specific atom, allowing them to create a “sea” of electrons around positively c...

Ionic bonding is the process where metals transfer electrons to non-metals, resulting in the formation of positively charged cations and negatively charged anions. This transfer leaves both elements with full outer electron shells, resembling the electronic configuration of noble gases. The electros...

The text discusses the concept of electronegativity, defined as the ability of an atom to attract electrons in a covalent bond. It highlights trends in electronegativity across the periodic table, noting that it increases across a period and decreases down a group. The Pauling scale is introduced as...
