Radioactive decay happens in an unstable isotope of a given element, as the isotope decays radiation is given off. As for when exactly, the decay of a nucleus is spontaneous and random so averages are used, these averages are different for different isotopes, but are measured as the "half life" (the time it takes for half the nucleus to decay).

Why alpha emission occur first?
The question is unclear. First before what? More likely to occur? I am going to assume the latter... Alpha decay is more likely to occur, when both alpha and beta are possible, because alpha decay removes more binding energy from the nuclide, and the tendency is to reduce energy as quickly as possible.
How can nuclear changes occur?
These can happen by fission where a nucleus splits into two parts on absorbing a neutron, or by radioactive decay.
Order gamma decay beta decay and alpha deacy form weakest to strongest?
gamma decay beta decay alpha decay
What is relative decay?
I believe relative decay is the decay over time.
What does the decay of actinium turn into?
The natural isotope 227Ac decay: - by beta minus decay: to 227Th - by alpha decay: to 223Fr
What gas helps decay to occur?
Any gas helps decay to occur.
When is it possible for decay not to occur?
The physical and chemical decay is not possible in vacuum but nuclear decay can neither be stopped.
Does transmutation occur in gamma decay?
No
Does not occur the endometrium will decay and a woman will menstruate is called?
fertilization
How does tooth decay occur?
Not keeping your teeth clean and healthly
Why doesn't alpha decay occur for hydrogen?
Alpha decay requires two protons and two neutrons. Hydrogen only has one proton.
Which noble gas occur when decay of uranium and radium occurs?
This noble gas is radon.
During the beta decay the following change will occur in the nucleus's.?
A neutron changes to a proton.
Why branching decay occur in thorium series?
Thorium-232 is appearing in the thorium series.
Does beta decay occur during the rearrangement of protons and neutrons in the nucleus?
No. Beta decay occurs when the Weak Force transforms a neutron to a proton or vice versa.

Radioactive decay can be affected by what?
Most types of radioactive decay cannot be affected by anything. However, radioactive decay involving electron capture will be affected by the removal of electrons from around the nucleus. In the absence of orbital electrons, it cannot occur at all.
