Question

Write the electron-dot structure for sodium, oxygen and magnesium.

Answer 1

The representation of elements with valence electrons as dots around the elements is referred to as electron-dot structure for elements.
$\text{(a) Sodium}(2,8,1)=\dot{\text{Na}}\text{(b) Oxygen}(2,6)=\ddot{:\text{O}:}\text{(c) Magnesium}(2,8,2)=\ddot{\text{Mg}}$
