The hydroxonium ion, H3O+ Oxygen is in group 6 - so has 6 outer electrons. Add 1 for each hydrogen, giving 9. Take one off for the +1 ion, leaving 8.

WebbIn physics, a gas is a state of matter, consisting of a collection of particles (molecules, atoms, ions, electrons, etc.) without a definite shape or volume that are in more or less random motion. Gases are compressible and change volume when placed under pressure or are heated or cooled.

It is the outer shell or valence shell electrons which are responsible for forming bonds and it is the arrangement of these electrons which determine molecular shape. The electrons are all negatively charged and so will repel each other.
