Explanation:
Bellow are the structures of the elements circled usind the element builder gizmo.
To know for further activities, when asked to draw the electron dot diagram the nucleous of the atom is represented by its chemical symbol and the electrons are represented by dots.
The number of electrons:
- If the atom is in neutral state, the number of electros matches the atomic number
- If it's ionized, the number of electros is equal to the atomic number minus the charge of the atom.
For example: O-2 (oxygen anion)
\(n_{electrons}=8-(-2)=10\)
