a Proton. A hydrogen-1 atom (the most abundant isotope of hydrogen) has no neutrons and only 1 proton. So the atom is 1 proton and 1 electron.
So the ion, when the electron is removed, the entire ion is just 1 single proton.

Hydrogen H+ ion is (i.s.o. 'can be thought of as ...) one proton.
The hydrogen isotope ; protium. It has one proton and one electron only. However the other two isotopes of hydrogen do contain all three sub-atomic particles. Deuterium ; one proton, one neutron and one electron. Tritium ; one proton, two neutrons, and one electron. All three isotopes are Hydrogen because they all contain ONE proton. The most common isotope is protium , which is casually thought of a hydrogen. Deuterium (D) is 'heavy hydrogen' and used in the nuclear industry. Tritium (T) is 'super heavy hydrogen' and is radio active and the rarest isotope of hydrogen. NB All other atoms of elements in the Periodic Table contain protons, neutrons and electrons.
Hydrogen ions (H+) can be thought of as protons.
Because it's made of gas, mostly hydrogen, with - it is thought - a small solid core made of rock and metallic hydrogen.
it helped contain disease.
The planet Jupiter is predominantly made up of hydrogen and helium. The core of planet is thought to contain some rock and metallic hydrogen, but Jupiter is mainly made up of gas, hence its classification as a gas giant.
Space is thought as a vacuum but it does contain small amounts of gases. It is mainly comprised of hydrogen plasma particles. There is no nitrogen that has been found in open space yet.
The proton and the neutron reside in the nucleus.
Most elements exhibit isotopes. Taking hydrogen as an example. It has three isotopes, viz. Protium, Deuterium , and Tritium. Protium (H-1)contains 1 proton and 1 electrons. It is the commonest isotopes of hydrogen, and is what is commonly thought of as hydrogen. Deuterium (H-2 /(D))contains 1 proton , 1 electron and 1 neutron. It is sometimes referred to as 'Heavy hydrogen' and is used to make 'Heavy water' for nuclear reactors. etc., Tritium (H-3 /(T))contains 1 proton , 1 electron and 2 neutrons. It can be thought of as 'Super heavy hydrogen'. It is the least comment isotope, known only in trace amounts, and is Radio-Active. Notice all isotopes of hydrogen contain only ONE proton and ONE electron , but the number of neutrons varies. Other well known isotopes are Carbon-12 / -13/-14 and Chlorine =35/-37 and uranium-235/-236-238
There is thought to be a molecular hydrogen layer, and a liquid metallic hydrogen layer. At high pressures, hydrogen forms a liquid metal which is a very good electrical conductor. We think this because combined with rapid rotation, a dynamo is formed, producing Jupiter's intense magnetic field. There is also thought to be a rocky core that was formed by planetesimals, which basically supplied the initial gravity to hold the gases and create a gigantic gaseous planet.
