There is a simple difference between a nucleus and a nucleon. A nucleus is at the center of an atom, and it is that collection of particles, protons and neutrons, that make up the nucleus of that atom. Because atomic nuclei are composed of protons and neutrons, we have come up with the term nucleon to describe any particle that makes up an atomic nucleus. That means either a proton or a neutron, when we talk about them as part of the nucleus of an atom, can be properly called a nucleon. The nucleus of an atom is said to be made up of nucleons. It's just that simple.
The difference between a nuclide and a nucleon is that nucleons determine which nuclide we're considering. Let's look. Nucleons are the particles that make up an atomic nucleus. That means either a proton or neutron in an atomic nucleus could be fairly referred to as a nucleon. The term nuclide is one that is applied to say something like "the atom that has a nuclear configuration of _____." In the nuclide helium-4, the helium atom has 4 nucleons. There are the 2 protons, naturally, and a pair (2) neutrons. The 4 nucleons give it that isotopic number 4. In hydrogen-2, this nuclide has 2 nucleons, a proton and a neutron, in its nucleus.
The nucleus of a radioactive atom has an unusual number of neutrons, or is too large, and is unstable.
Carbon-12 (6 protons, six neutrons) is stable, but the isotope Carbon-14, with two extra neutrons, is unstable and thus radioactive, for example.
They are both the same thing, just different words to describe it.
nucleus is one of them and nuclei are two.
Nucleus is an area of the cell bounded by nuclear membrane, where chromatin and nucleolus reside. A Nucleoid is an area of the cytoplasm of the prokaryote where DNA is localized
It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.
Pressure does not affect the rate of radioactive decay. That is entirely unaffected by the environment within the nucleus of the atom.
No. Nuclear reactions are not chemical reactions. They involve changes to the nucleus of the atom, such as radioactive decay.
Yes. A radioactive atom is a radioactive atom. If that atom exists as a single atom and is uncombined and it is radioactive, it's radioactive. If that same atom is chemically combined with another or other atoms, it's still radioactive. It's just that simple.
NUCLEUS.Atomic energy is produced from changes within nucleus of an atom.
A radioactive atom is an atom of an element with an unstable nucleus.
It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.
They originate in the nucleus of the atom.

It is the nucleus of the atom that undergoes change during radioactive decay.
