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.

How many protons does a standard hydrogen have?

A standard hydrogen atom has 1 proton. The Atomic Number of any element is the number of protons that element has.


How many neutrons are in the atom of Hydrogen?

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.


Protons in water molecule?

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.


Which subatomic particle identifies an atom of a particular element?

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.


How are two isotopes of an element different?

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.

What determines the atomic number for hydrogen?

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.


What is the total number of protons in the compound, including both protons from the hydrogen atoms (Ha and Hb)?

The total number of protons in the compound, including both protons from the hydrogen atoms (Ha and Hb), is 6.


How many protons does hydrogen-1 have?

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.


Isotopes of hydrogen have the same what?

Same number of protons, different number of neutrons


How are the number of protons in an element determined?

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.


Can the atom of hydrogen does not have a proton in its necleus?

no. elements are categorized by the number of protons. also if there are no protons. then it is no longer an atom


How many protons does a standard hydrogen have?

A standard hydrogen atom has 1 proton. The Atomic Number of any element is the number of protons that element has.


Can hydrogen atoms have more than one proton?

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.


Do hydrogen and atoms have an equal number of electrons?

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.


What is the mass number of hydrogen?

The mass number of the most common hydrogen isotope, Hydrogen-1, is one


How many protons are there per atom?

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.


What is the number of protons of hydrogen-1?

Hydrogen will always have 1 proton regardless of the isotope.
