Answer 1

hiii dear student,

Answer 2

Oxygen is in Group 6 (sometimes called Group VI or Group 16). Since it is in Group 6 it will have 6 valence electrons. When you draw the Lewis structure for Oxygen you'll put six "dots" or valance electrons around the element symbol (O).


Sodium is in Group 1. Since it is in Group 1 it will have 1 valence electrons. When you draw the Lewis structure for Sodium you'll put one "dot" or valance electron next to the element symbol (Na).


Magnesium is in Group 2 (sometimes called Group II or 2A). Since it is in Group 2 it will have 2 valence electrons. When you draw the Lewis structure for Magnesium you'll put two "dots" or valance electrons around the element symbol (Mg).

Hope this helps you
