The atomic structure and periodic trends guide explores key concepts in atomic properties and bonding patterns.

Trends in atomic radius across periods show a consistent decrease due to increased nuclear attraction
Ionisation energy exceptions in periodic table occur notably in groups 2/3 and 5/6
Melting points across period 2 and 3 in chemistry demonstrate varying patterns based on bonding types
• Successive ionisation energies provide insights into electron configuration and group determination
• Intermolecular forces play a crucial role in determining physical properties

Melting Points and Molecular Structure

This page details the relationship between melting points and molecular structure across periods 2 and 3. The trends vary significantly based on bonding types and molecular arrangements.

Definition: Melting point is the temperature at which a solid transitions to a liquid state.

Example: In period 3, elements like sodium (Na) and magnesium (Mg) show increasing melting points due to stronger metallic bonding.

Highlight: Covalent structures with multiple bonds require more energy to break, resulting in higher melting points.

Vocabulary: IMF (Intermolecular Forces) are the attractive forces between molecules that influence physical properties like melting point.

Atomic Structure and Ionisation Energy

This page explores fundamental atomic properties and ionisation energy trends across the periodic table. The atomic radius demonstrates predictable patterns, decreasing across periods due to stronger nuclear attraction to outer electrons. Ionisation energies follow specific trends with notable exceptions.

Definition: Ionisation energy is the energy required to remove one outer electron from each atom of gaseous atoms to form ions.

Example: Sodium (Na) ionisation process: Na(g) → Na+(g) + e-

Highlight: The biggest jump between successive ionisation energies indicates an element's group position in the periodic table.

Vocabulary: Electron shielding refers to inner electrons reducing the nuclear attraction to outer electrons.
