Question

Just for questions please help me

Gamma rays are unlike alpha and beta particles because gamma rays:
are more strongly deflected by electric or magnetic fields
have less energy than either alpha or beta particles
have more mass than either alpha or beta particles
have no effect on atomic number or mass number of the atoms that emit them

What would be the effect on the nucleus of an atom if it emitted one alpha particle and one gamma ray?
a decrease of two in atomic number and a decrease of four in mass number
an increase of one in atomic number and a decrease of two in mass number
an increase of one in atomic number and an increase of two in mass number
an increase of two in atomic number and an increase of four in mass number

When a gamma ray is emitted from the nucleus of an atom:
it reduces the overall energy of the nucleus
it increases the overall energy of the nucleus
it causes a charge imbalance in the nucleus
it causes changes in the electronic structure outside of the nucleus

What would be the effect on the nucleus of an atom if it emitted one alpha and then one beta particle?
a decrease of two in atomic number and a decrease of four in mass number
a decrease of one in atomic number and a decrease of four in mass number
a decrease of one in atomic number and an increase of one in mass number
an increase of one in atomic number and a decrease of two in mass number

*please chcek my answers for the picture

Answer 1

1.I would say the last one because unlike beta and alpha rays they will have no effect on the mass or atomic number because they are just composed of high energy radiation

3.When a radioactive nucleus emits an alpha particle or

a beta particle, the protons, and neutrons in the new nucleus
may not be in their most stable arrangement. The protons and
neutrons can rearrange themselves to become more stable
and in this process, energy is emitted in the form of gamma rays.

Sorry only know 1 and 3
