draw the lewis structure for the (h₃o⁺) ion.
Answer
Explanation:
Step1: Count valence electrons
Oxygen has 6 valence - electrons, each hydrogen has 1 valence - electron, and the ion has a + 1 charge (subtract 1 electron). So, (6+(3\times1)-1 = 8) valence electrons.
Step2: Determine the central atom
Oxygen is the central atom as hydrogen can only form one bond.
Step3: Connect atoms with single bonds
Connect the oxygen atom to each of the three hydrogen atoms with single bonds ((O - H)). Each single bond uses 2 electrons, so (3\times2 = 6) electrons are used so far.
Step4: Place remaining electrons
We have (8 - 6=2) electrons left. Place these 2 electrons as a lone - pair on the oxygen atom.
Answer:
The Lewis structure has an oxygen atom in the center with three single bonds to hydrogen atoms and one lone - pair of electrons on the oxygen atom. The overall structure has a positive charge.
