What does it mean by the statement The decay of unstable radioactive nuclei is totally random?

It means that you can't predict when an individual atom will decay.
If a certain isotope has a half-life of 5000 years, that means that if you have a large number of atoms, half of them will decay after 5000 years. After another 5000 years, half of what is left will decay - only 1/4 of the original amount is left.
For an individual atom, in the above example, there is a probability of 50% of decaying within 5000 years, a probability of 75% of decaying within 10,000 years, etc.

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.
Process by which unstable nuclei lose energy?
Radioactive decay
Unstable atomic nuclei decay over time into stable nuclei causing a mineral to be?
radioactive
Radioactive materials have unstable?
It's Nuclei, the past answers are wrong.
How do nuclear atoms differ from regular atoms?
All atoms are nuclear, in that they all have nuclei. Some atoms have unstable nuclei, making them radioactive. I'm afraid I have no idea what you mean by "nuclear atoms," unless you meant to say radioactive atoms, in which case the answer is "they have unstable nuclei and they're radioactive."
What is a nucleus that is unstable and undergoes decay?
Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
What is released when unstable radioactive nuclei disintegrates?
energy and fast-moving particles are released,
What is the spontaneous process through which unstable nuclei emit radiation?
Radioactive decay or radioactivity
Will unstable nuclei all undergo radioactive decay in order to gain stability?
Yes
What term indicates the process in which unstable nuclei releases radiation?
The term is "radioactive decay".
Where do the two neutrons and two neutrons that consist on alpha particle come from?
they come from the nuclei of an unstable atom.
What is the difference between radioactive and non radioactive materials?
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non radioactive substances are stable.
