Description

Properties of Elements Across a Period

As you move from left to right across a period, elements transition from metals to non-metals. Metals are typically good conductors, while non-metals are poor conductors and can be gases, liquids, or brittle solids.

  1. a

    Explain the transition of properties from metallic to non-metallic as you move across a period.

    Aim for approximately 3 distinct marking points.
