Question

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

Answer 1

→ When the valence electrons are represented as dots circling the elements it is known as the elemental structure with electron –dot. Thus for option i) we can write Sodium (2, 8, 1) = Na with one electron at the top. ... In Na2O, Na+ and O2- ions are present and in MgO, Mg2= and O2 (2- ) ions are present.
