What happens to the atomic number of the nucleus of an element when an α-particle is emitted?

What will be the change in atomic number and atomic mass of an element 𝑋𝑧𝐴, when two alpha particles are emitted from its nucleus?

f one alpha particle and two beta particles are emitted, what is the atomic mass number of the newly produced element?

Which of the following changes occur within a nucleus when it emits an alpha particle?Its mass number increases by 4 and its atomic number increases by 2Its mass number decreases by 2 and its atomic number decreases by 2Its mass number decreases by 4 and its atomic number decreases by 2Its mass number increases by 2 and its atomic number increases by 22Which of the following changes occurs within a nucleus when it emits a beta (minus) particle?Its mass number stays the same and its atomic number decreases by 1Its atomic number stays the same and its mass number decreases by 1Its mass number stays the same and its atomic number increases by 1Its atomic number stays the same and its mass number increases by 13Which of the following things will NOT occur when a nucleus undergoes gamma decay?The nucleus will move to a lower-energy stateThe atomic number of the nucleus won’t changeA short-wavelength, high-frequency electromagnetic wave will be emitted from the nucleusThe mass number of the nucleus will decrease4Polonium-194 is formed by the alpha decay of radon-198.  There are 84 protons in the nucleus of a polonium-194 atom.  Calculate the number of neutrons in the nucleus of an atom of radon-198.84112110865Which type(s) of nuclear radiation will be stopped by a sheet of aluminium?Alpha particles, beta particles and gamma raysBeta particles onlyAlpha particles onlyAlpha particles and beta particles6Which of the following changes occurs within a nucleus when it emits a neutron?Its atomic number stays the same and its mass number decreases by 1Its mass number stays the same and its atomic number increases by 1Its mass number stays the same and its atomic number decreases by 1Its atomic number stays the same and its mass number increases by 1
