Answer :
An atom is constructed of three different particles known as electrons, protons and neutrons.
An atom is neutrally charged because the charge/number of the electrons (negative charge ) is equal to the charge/number that the proton carries (positive charge). these charges cancel out each other making the atom neutrally charged.
Model of an ionized atom
An ionized atom is the one which has some net charge present on it. It can be either a positive charge or a negative charge.
Model of radioactive atom
A radioactive atom is one an unstable atom and has access of energy in its center. It can be caused by adding either neutrons or protons.
To Model a radioactive atom, increase the number neutron or proton present in the nucleus.
Hence, we can conclude that to model an ionized atom is done by adding or removing electron(s) from the atom while to model a radioactive atom we add additional Neutron or proton to the nucleus.
