Key Concepts

Periodic Table Structure

• Groups (1-18): Similar valence electron configuration
• Periods (1-7): Same shell number
• Blocks: s, p, d, f based on orbital filling

Chemical Periodicity

# Example: Periodic trend calculations
periodic_trends = {
    'atomic_radius': {
        'across_period': 'decreases',
        'down_group': 'increases'
    },
    'ionization_energy': {
        'across_period': 'increases',
        'down_group': 'decreases'
    },
    'electronegativity': {
        'across_period': 'increases',
        'down_group': 'decreases'
    },
    'electron_affinity': {
        'across_period': 'generally increases',
        'down_group': 'generally decreases'
    }
}
