No partial or complete atom has anywhere near 12,000 times the mass of
a hydrogen atom.
The mass of the hydrogen atom is 1 Atomic Mass unit (AMU), corresponding to
the single proton in its nucleus.
The largest, most massive atom that presently occurs naturally on Earth is that
of Uranium. The heaviest form of Uranium has 238 protons and neutrons in its
nucleus, for an atomic mass of around 238.
All of these mass numbers correspond to the number of protons and neutrons
in the nucleus. The electrons surrounding the nucleus are largely ignored, for
a few reasons:
-- Electrons come and go, get added to and separated from atoms, rather easily.
-- 1 proton or 1 neutron have as much mass as about 1,840 electrons, so a few
electrons more or less doesn't make much difference in the mass of an atom.
-- The most complex atom ... Uranium again ... normally has only about 92
electrons, which amounts to only about 5 percent of one proton or neutron,
so they don't have much impact on an atomic mass of 238 .

When a beta particle is released from an atom does the atom gain or lose mass?
The atom loses mass when a beta particle is released because a neutron decays into a proton, electron, and antineutrino. The mass of the neutron is greater than the combined mass of the resulting proton, electron, and antineutrino.
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
An equal mass of helium would contain fewer atoms compared to hydrogen, as each helium atom is four times heavier than a hydrogen atom. This is because the atomic mass of a helium atom is roughly four times that of a hydrogen atom.
How is a hydrogen atom is different than a proton?
A hydrogen atom consists of a proton in its nucleus along with an electron orbiting around it. A proton is a subatomic particle found in the nucleus of an atom and carries a positive charge. In comparison, a hydrogen atom is a neutral particle since it has an equal number of protons and electrons.
What particle consists of two protons and two neutrons it is the same as a helium nucleus release of a what particle by an atom decreases the atomic number by 2 and the mass number by 4?
The particle that consists of two protons and two neutrons, equivalent to a helium nucleus, is an alpha particle. When an atom releases an alpha particle, its atomic number decreases by 2 and its mass number decreases by 4.
How does the composition of an atom change when it emits a beta particle?
When a nucleus emits a beta particle, it loses one of its neutrons and gains one proton. Hence, it's mass and atomic number remain the same but its charge and What_happens_to_a_nucleus_when_it_emits_a_beta_particlenumber is increased by +1.
What can be considered to be the combination of a proton and an electron?
The pair form a hydrogen atom.There is a fallacy that's taught about this pairing, which is that the electron-proton pair form a neutron. See my answer to the question "What particle has the same mass as a hydrogen atom?" for more details about this, and why it is wrong.
Does an oxygen atom weight the same as a hydrogen atom?
an oxygen and a hydrogen atom do not weight the same
What is a neutral particle in the nucleus of atom with the same mass as a proton?
Neutron
How many hydrogen atoms make up the same mass as one sodium atom?
To find the number of hydrogen atoms that make up the same mass as one sodium atom, you need to compare the atomic masses. A sodium atom has an atomic mass of 23 daltons, while a hydrogen atom has an atomic mass of 1 dalton. Therefore, 23 hydrogen atoms make up the same mass as one sodium atom.
When a beta particle is released from an atom does the atom gain or lose mass?
The atom loses mass when a beta particle is released because a neutron decays into a proton, electron, and antineutrino. The mass of the neutron is greater than the combined mass of the resulting proton, electron, and antineutrino.
What is the name for a nuclear particle that has about the same mass as a proton but with no electrical charge?
The nuclear particle that has about the same mass as a proton but no electrical charge is called a neutron. Neutrons are found in the nucleus of an atom along with protons and contribute to the atomic mass of the atom.
What is the proton for xenon?
A proton is a subatomic particle which is the same in whichever element it is found. A proton from a Xenon atom is no different to that from a Hydrogen atom or a Uranium atom.
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
An equal mass of helium would contain fewer atoms compared to hydrogen, as each helium atom is four times heavier than a hydrogen atom. This is because the atomic mass of a helium atom is roughly four times that of a hydrogen atom.
How is a hydrogen atom is different than a proton?
A hydrogen atom consists of a proton in its nucleus along with an electron orbiting around it. A proton is a subatomic particle found in the nucleus of an atom and carries a positive charge. In comparison, a hydrogen atom is a neutral particle since it has an equal number of protons and electrons.
Who has greater kinetic energy a hydrogen atom or a carbon atom moving at the same speed?
The carbon atom would have greater kinetic energy compared to the hydrogen atom because kinetic energy is directly proportional to the mass of the object. Since the carbon atom is heavier than the hydrogen atom, it would possess more kinetic energy when moving at the same speed.
Is a particle an atom?
No, a particle is not the same as an atom. A particle is a small piece of matter, while an atom is the smallest unit of an element that retains the properties of that element.
What particle consists of two protons and two neutrons it is the same as a helium nucleus release of a what particle by an atom decreases the atomic number by 2 and the mass number by 4?
The particle that consists of two protons and two neutrons, equivalent to a helium nucleus, is an alpha particle. When an atom releases an alpha particle, its atomic number decreases by 2 and its mass number decreases by 4.
