Atomic Structure and Periodicity · Atomic Structure

Periodic Patterns in Properties

Examining the physical and chemical trends across Period 3 elements and their oxides.

Key Questions

  1. 1How does the nature of bonding in Period 3 oxides change from ionic to covalent?
  2. 2Why does the atomic radius decrease across a period despite an increase in the number of electrons?
  3. 3How can we predict the pH of an oxide based on its position in the periodic table?
