the first isotope of hydrogen
The nucleus of a hydrogen atom is formed by a single proton.
The "NUMBER" (#) of Protons in an Atom of Hydrogen is one (1). The number of protons is what makes a specific element that element. Hydrogen always has one proton no matter what. If someone says that a hydrogen atom has two protons(they are incorrect), it is no longer hydrogen; it is the element Helium.
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.
1 proton and 1 electron make a hydrogen atom. The proton carries a positive charge, and the electron carries a negative charge, creating a stable neutral atom.
Hydrogen
Hydrogen
Of the common sub-atomic particles, both the proton and the neutron have mass numbers of 1.
The answer for a hydrogen atom would be about 100 meters across a proton is about 1/10,000 th of the diameter of a hydrogen atom.
The atomic number is equivalent to its number of protons. One proton in atom is its atomic number is 1. Hydrogen is the only atom with one proton.
Proton has uni-positive charge and is found within the nucleus
Hydrogen has one proton in its nucleus.
Hydrogen always has 1 proton. If it had two, it would then become Helium. The fact that it is a Hydrogen ion, just means that it is not electrically neutral. Since the proton is what defines the atom, the Hydrogen atom must be missing an electron, leaving the atom with a net positive charge of +e.
