Protons and electrons both have mass. Therefore a hydrogen atom that contains one or both will have mass. (It will, however, be less massive than a hydrogen atom that also has neutrons.)

What type of particle has an atomic number of 1 and a mass number of 1?
Of the common sub-atomic particles, both the proton and the neutron have mass numbers of 1.
A hydrogen atom that has mass number of 1?
This is called also protium and contain 1 proton and 1 electron.
What are the protons in hydrogen atom?
The proton is an elementary particle with the mass 1.00727646677 atomic units of mass and the electrical charge +1. It is a hydrogen ion in which one electron is lost. But since hydrogen only has one electron and one proton, a hydrogen ion is just called a "proton", since only a proton is left.
An atom of tritium an isotope of hydrogen has 1 proton 2 neutrons and 1 electron What is its mass in amu?
Three
What is a charged particle that accounts for nearly half the mass of an atom?
The proton.The proton is a particle of the nucleus (a nucleon) of charge +1. Neutrons are nucleons with no charge, are slightly more massive than a proton, and are part of every atomic nucleus except for the simplest, Hydrogen (there are exceptions, of course, in deuterium and tritium, but here we will keep to simple Hydrogen.)Electrons are tiny by comparison, and are not a part of the nucleus. They "orbit" at some distance. They provide the -1 charge to balance the charge of a proton, but they have a very low mass, 1/1836 that of a proton.Except for the atom Hydrogen, where the proton is practically all the mass of the atom, the proton is the charged particle which accounts for nearly half of the mass of any atom.
Is hydrogen the smallest particle of an element?
An average hydrogen atom consists of 1 proton and 1 electron. The 1 proton accounts for nearly all of that atom's mass. The 1 electron has only about 1/2000th the mass of the proton. That's about 0.0005 of the total atomic mass.
Which has an atomic mass unit of 1?
A hydrogen atom of the most common isotope of hydrogen, or a proton or neutron.
Is the mass of a hydrogen atom different from the mass of an oxygen atom?
all atoms have different masses Mass of an atom is due to protons and neutrons present in an atom and number of proton is something that distinguish between atoms, therefore mass of hydrogen is different to the mass number of oxygen, hydrogen's mass is 1 as it has only 1 proton and no neutrons, and oxygen mass's is 16 as it has 8 protons and 8 neutrons.
What type of particle has an atomic number of 1 and a mass number of 1?
Of the common sub-atomic particles, both the proton and the neutron have mass numbers of 1.
Which two particles make up most of the mass of a hydrogen-2 atom?
The proton and the neutron make up most of the mass of a hydrogen-2 atom.
A hydrogen atom that has mass number of 1?
This is called also protium and contain 1 proton and 1 electron.
What are the protons in hydrogen atom?
The proton is an elementary particle with the mass 1.00727646677 atomic units of mass and the electrical charge +1. It is a hydrogen ion in which one electron is lost. But since hydrogen only has one electron and one proton, a hydrogen ion is just called a "proton", since only a proton is left.
What element has 1 proton in each atom?
Hydrogen has one proton in its nucleus.
An atom of tritium an isotope of hydrogen has 1 proton 2 neutrons and 1 electron What is its mass in amu?
Three
Because a hydrogen atom does not contain a neutron hydrogen ions can be thought of as what?
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.
Which atom has 1 proton in its nucleus?
Hydrogen
What atom has 1 proton in its nucleus?
Hydrogen
