Use the periodic table to predict the valence electron configuration of all the elements of group 2 (beryllium, magnesium, calcium, strontium, barium, and radium). Given: series of elements. Asked for: valence electron configurations. Strategy:
May 28, 2024 · In this example, the group number is provided using the "A/B System," so the correct box can be found by counting down from the top of the periodic table (to find the appropriate period) and then across the columns corresponding to the main group elements (to find the proper group).
Questions and model answers on 3.2 Group 2 for the OCR A Level Chemistry syllabus, written by the Chemistry experts at Save My Exams.
Group 2 elements are s-block elements because their outermost electrons are in the s-orbital. They have two electrons in their outermost shell, leading to their tendency to lose two electrons in reactions to achieve a stable electron configuration. Group 2 elements are all metallic and shiny.
