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 change in mass occurs when a radioactive atom emits an alpha particle?
4 from the alpha. Betas have negligible mass and gammas have no mass.
Which particle does not change in amount in an atom?
The particle in an atom that cannot change is the number of protons. If that changes, it is no longer the same element.
Which particle of the atom has no change?
Nucleus
What is lost from the nucleus of atom when it emits an alpha particle?
When an atom emits an alpha particle, it loses two protons and two neutrons from its nucleus. This results in a new element being formed with an atomic number that is two less than the original element.
Over time what will happend to the nucleus of a radioactive atom If a radioactive atom emits an alpha particles them what is it emitting?
Alpha particle is the same as a helium-4 nucleus, i.e., two protons and two neutrons bound together. If an atom emits an alpha particle, it will have two protons less, and two neutrons less. Over time, there may be additional decay, which may further change the number of protons and neutrons.
What change in mass occurs when a radioactive atom emits an alpha particle?
4 from the alpha. Betas have negligible mass and gammas have no mass.
What is the change in the atomic number when the atom emits an alpha particle?
The atomic number will decrease by 2, the number of protons in the emitted alpha particle. An alpha particle is a helium-4 nuclei with two protons and two neutrons.
How does the composition of an ion differ from the composition of a non ionic particle?
An ion has a net electrical charge; a nonionic particle that is at least as large as an atom does not.
Which particle is emitted when an atom OF 85Kr spontaneously decays?
When an atom of 85Kr spontaneously decays, it emits a beta particle. This decay process involves the transformation of a neutron into a proton, with the emission of an electron and an antineutrino.
Which particle does not change in amount in an atom?
The particle in an atom that cannot change is the number of protons. If that changes, it is no longer the same element.

What is a radioactive atoms?
Radioactive atoms are atoms that have unstable nuclei, which can undergo radioactive decay to become more stable. During this process, they emit radiation in the form of alpha particles, beta particles, or gamma rays. This emission of radiation can cause a change in the atom's composition or energy level.
Can an atom gain or lose protons why or why not?
No, an atom cannot gain or lose protons. Protons are the positively charged particles within the nucleus of an atom, and changing the number of protons would change the atom's identity. However, atoms can gain or lose electrons, which affects their charge but not their identity.
In the process of radioactive decay when one atom emits say one alpha particle why the product is referred to as another downstream atom and not an ion?
When a parent atom undergoes radioactive decay and emits an alpha particle, the resulting product is called a daughter atom rather than an ion because the process involves a change in the nucleus of the atom. The emitted alpha particle is a helium nucleus (2 protons and 2 neutrons) which is ejected from the nucleus of the parent atom. This causes the identity of the atom to change, resulting in a new element (daughter atom) with different chemical properties rather than just creating an ion of the original element.
What change in atomic mass when an atom emits gamma radiation?
It remains the same.
