Question

What is the lewis dot structure for O, H, Mg and P

Answer 1

Here are the Lewis (electron‑dot) pictures for the neutral atoms (showing valence electrons):

- H (1 valence e): H·

- Mg (2 valence e): ··Mg (or :Mg: — a pair of electrons)

- O (6 valence e): two lone pairs and two single electrons, e.g.
:
· O ·
:

- P (5 valence e): one lone pair and three single electrons, e.g.
·
: P ·
·

(Colons ":" represent electron pairs; single dots "·" are unpaired valence electrons.)
