The beta particle will alter the electromagnetic field of the atom. An electron will add to the electromagnetic charge if emitted, and subtract from, if it is absorbed. A positron will do the opposite. The atomic nucleus will also change. an electron can convert a neutron to a proton if emitted, and a proton to a neutron if absorbed. The positron, again, will do the opposite.
No, an input of energy is not required for nuclear decay to happen in an atom. Nuclear decay is a spontaneous process that occurs when an unstable nucleus emits particles or energy to become more stable.
The absorption spectrum of an atom shows that the atom emits that spectrum which it absorbs.
The electron in the atom becomes excited as something adds energy to it, moving it to a higher energy level. When the electron moves back to the normal energy level, called a ground state, it emits light of a given frequency.
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.
If an atom forms from its constituent particles, the protons and neutrons would come together in the nucleus, surrounded by electrons in energy levels. The atom would have a neutral charge and would be stable unless it undergoes interactions with other atoms or particles.
Alpha particles are emitted from the atom taking with it 2 protons and (I am pretty sure) two neutrons. This will change the atomic number of the atom and the atomic weight.
The atoms structure is unstable and it emits alpha or beta particles that changes the Atom

No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.

This is a radioactive isotope.
In an atom of antimatter, that would be true, in an atom of matter that would be false.
