Is it true that a unstable nuclei will undergo radioactive decay in order to gain stability?
It is true that unstable nuclei will undergo radioactive decay in order to gain stability. These include nuclei of #43 Technitium (Tc), any nucleus containing more that 83 protons and any nucleus with a high neutron-to-proton ratio, such as carbon-14. The most common forms of decay are by emission of an alpha particle (2 protons and 2 neutrons ... a helium nucleus!) or a beta-negative decay in which a neutron bcomes a proton by emitting an electron and an antineutrino.
What kind of decay is it when a nuclear reaction in which a neutron is transformed into a proton and in electron?
When a neutron -> proton, it is called a Beta - (minus) decay.
What is nuclei that has unstable decay known as?
Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
Does atomic mass stay the same?
The atomic mass of a radioactive atoms is changed during the radioactive decay (alpha decay, neutron decay, proton decay, double proton decay), spontaneous or artificial fission, nuclear reactions.
Do proton-proton chain convert four hydrogen nuclei into one helium nucleus?
Yes

What is a hydrogen nuclei?
Most commonly, a hydrogen nuclei is simply a proton. If you are dealing with a hydrogen isotope (H2 or H3) then it is a proton and 1 or 2 neutrons. Most commonly, a hydrogen nuclei is simply a proton. If you are dealing with a hydrogen isotope (H2 or H3) then it is a proton and 1 or 2 neutrons.
Does the proton decay?
This all depends on the situation and context. In particle physics, proton decay is hypothetical. It is a type of radioactive decay where protons decay into lighter subatomic particles.
A beta particle may be spontaneously emitted from?
Positrons are emitted from proton-rich radioactive during positive beta-decay.
Why do nuclei decay?
To become stable
What kind of decay is it when a nuclear reaction in which a neutron is transformed into a proton and in electron?
When a neutron -> proton, it is called a Beta - (minus) decay.
Why are positrons produced from some nuclei but alpha or beta radiation come from other nuclei?
Positrons are a type of beta radiation (along with electons). Let's check things out to figure out why some nuclei are positron emitters. Positron emission (beta + decay) follows after the conversion of a neutron in an atomic nucleus into a proton. In atomic nuclei that have an excess number of neutrons to be stable, this is a common form of decay. It directly assists an unstable nucleus in getting closer to the "line of stability" of the N-Z plot. As beta + decay has a higher probablity for nuclei with excessive numbers of neutrons, beta - decay has a higher probability for nuclei with shortages of neutrons. In general, alpha decay is reserved for the heaviest radionuclides. We see radium, uranium, plutonium and a number of other elements from the upper end of the periodic table as having alpha decay as a possibility among their methods of decay.

How electron is converted into proton?
An electron will not decay into a proton by any means.

Does atomic mass stay the same?
The atomic mass of a radioactive atoms is changed during the radioactive decay (alpha decay, neutron decay, proton decay, double proton decay), spontaneous or artificial fission, nuclear reactions.
What causes nuclear decay?
The instability of the nuclei is the basic cause of radioactive decay.
Why is decay necessary?
Those elements undergo the 'decay' process which have unstable nuclei so decay is necessary to gain the stability. such elements form the smaller stable nuclei as Lead nucleus.
