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 standard hydrogen atom has 1 proton. The Atomic Number of any element is the number of protons that element has.
The number of neutrons in a hydrogen atom will depend on which isotope of hydrogen we consider. Not all hydrogen atoms have the same number of neutrons. The vast majority of hydrogen atoms (over 99.98%) have no neutrons at all. Some have 1 (and this is called deuterium) and some have 2 (called tritium). These two isotopes occur naturally but are rare, as can be seen.To determine the number of neutrons in an atom, you must use the mass number, which is the sum of the number of protons and the number of neutrons. Since the atomic number of the element (for H, the atomic number is 1) tells you the number of protons, you can find the number neutrons by subtraction.See the Related Questions to the left for how to count the number of protons, neutrons and electrons in any atom of any element.
Water isn't an atom, its a molecule. One molecule of water is two hydrogen atoms (1 proton each) and one oxygen atom (8 protons each). Thus the total protons is 1+1+8 = 10 protons in one molecule of water.
It's the count of one of the subatomic particles in the nucleus, the proton, that is significant in this regard. For example, an atom is hydrogen if and only if it has one proton in its nucleus. It is neon if and only if it has ten protons in its nucleus.
An isotope is an element with the same number of protons, but a different number of neutrons. The same no of protons means the same no of electrons, and this means the same chemical properties. The difference in the no of neutrons means various changes in the physical properties such as density, and also the stability ( or lack of it ) of the nucleus.
The atomic number of all elements including Hydrogen is detemined by the number of protons it has for example, Helium's atomic number is 2 because it only has 2 protons.
The total number of protons in the compound, including both protons from the hydrogen atoms (Ha and Hb), is 6.
HydrogenAll atoms, ions, and isotopes of the same element have the same number of protons. The number of protons defines the element. Hydrogen atoms all have one proton. So it does not matter if you provide the mass number (hydrogen-1) because the number of protons does not depend on it. It does, however, let us know the number of neutrons. The mass number is the sum of the number of protons and neutrons. Because we know that hydrogen has one proton, and the mass number is one, there must be no neutrons.
Same number of protons, different number of neutrons
Well... the element number defines the number of protons, and usually the electrons. the neutrons are determined with... i dunno :P I.E. hydrogen is 1. Therefor, in hydrogen there are 1 protons and 1 electrons.
no. elements are categorized by the number of protons. also if there are no protons. then it is no longer an atom
A standard hydrogen atom has 1 proton. The Atomic Number of any element is the number of protons that element has.
No. Elements are given their names (like "Hydrogen" or "Gold") solely on their number of protons. If a Hydrogen atom had any other number of protons than one, it would not be a Hydrogen atom.
No. Neutral atoms of each element, including hydrogen, have a unique number of electrons, which is equal to the number of protons in their nuclei. The number of protons is the element's atomic number on the periodic table.
The mass number of the most common hydrogen isotope, Hydrogen-1, is one
The number of protons varies for different elements. For example, Hydrogen has only one proton in each atom. That's what makes hydrogen hydrogen. If it had two protons, it would be helium. If there were no protons, then it wouldn't be anything.
Hydrogen will always have 1 proton regardless of the isotope.
