Description

Group Number and Ion Charge

Elements in the periodic table are arranged in groups. Each group has specific characteristics regarding the charge of the ions they form. For example, Group 1 elements form +1 ions, while Group 2 elements form +2 ions.

  1. a

    State the charge of the ions formed by Group 1 elements.

    Aim for approximately 1 distinct marking point.
