Answer:
Lewis structure in the attached image.
Explanation:
To draw the Lewis structure of H₂SO₄, we need to consider the octet rule: atoms gain, lose or share electrons to have 8 electrons in their valence shell. Hydrogen is an exception because its valence shell is complete with 2 electrons (duet). H, S and O are nonmetals, so they form covalent bonds to complete their valence shell, that is, they share pairs of electrons.
- S has 6 valence electrons, so it has to share 2 pairs of electrons to reach the octet.
- O has 6 valence electrons, so it has to share 2 pairs of electrons to reach the octet.
- H has 1 valence electron, so it has to share 1 pair of electrons to reach the duet.
In the attached image is the resulting Lewis structure.
