What is the type of bonding on H3O?

Answer 1

Well with hydronium (H3O+) it starts off with a detached hydrogen ion floating in water. This usually happens when a compound with the potential to be acidic is dissolved in water, because when this compound is dissolved, it ionizes, and releases an H+ ion. The H+ on doesn't stay on its own for long though, because when the compound ionizes, it attatches to a water molecule, forming the H3O+ ion (hydronium). It is able to attach to a water molecule because water molecules are polar, meaning even though it may have a stable octet, there are places on the compound that are negative (like poles of a magnet). Since hydrogen has a positive force, it pulls towards negative "pole" of the water molecule and attaches itself to the water molecule. This forms H3O+ ion.
