The nucleus of an atom is composed of a single proton (usually), a proton and a neutron (rarely) or a proton and two neutrons (extremely rarely) in the case of hydrogen. I the case of all the other elements, both protons and neutrons will be present in varying quantities, depending on which element - and on which isotope of a given element - is being specified. The protons and neutrons are called nucleons when we refer to them as part of an atomic nucleus. A nucleon could be either a proton or a neutron in this case.
The nucleus consists of a small spherical mass of denser protoplasm (a jelly like substance), the nucleoplasm, surrounded by a membrane called nuclear envelope. It is found in the cytoplasm of the cell and controls the normal cell activities. Within the nucleus are the following. A) A network of long thread-like structures called chromatin. The chromatin threads contain hereditary materials. These materials control the activities of the cell. During cell division the chromatin threads condense and become highly coiled structures called chromosomes. Under the microscope the chromosomes appear as thick rod-shaped structures. Chemical analysis shows that each chromatin thread is made up of proteins and a compound called deoxyribonucleic acid or DNA. It is in the DNA that hereditary information is stored. B)Spherical structures called nucleoli. Each nucleolus plays a part in the building up of proteins. C)A nuclear envelope which separates the nucleus from the surrounding cytoplasm. The nucleus is responsible for the cell reproduction. It is needed for the continuing life of the cell, as well as for the repair of worn-out cells. Cells without a nucleus, for example, the red blood cells of a mammal have a short life span and are unable to reproduce.
The nucleolus is one part, it contains RNA and protein. The nuclear membrane is the next and it separates the nucleus from the cytoplasm. The last is the chromosomes, they are DNA and protein structures.

The basic structures are the nuclear envelope (pores allow for transport of materials), nuclear lamina (provides integrity to the envelope), chromosomes, nucleolus (assembles rRNA for ribosomes).
well the nucleus is the "Brain" of the cell but if you want a deeper answer it also have the part where the chromosomes are and deeper still is the genes which are small stripes in the chromosomes and deeper still we have the DNA strands.

neutron and proton
Protons and neutrons
The PROTONS and NEUTRONS. Collectively they are called ' nucleons'. Electrons are in energy shells around the nucleus.
The parts of the atom found outside the nucleus would be the electrons, or positrons if the nucleus of the atom is made of antimatter. The Heisenberg Uncertainty Principle shows us though that the electrons aren't found just in the space outside the nucleus, but in a probabilistic cloud, partly inside the nucleus.
Nuetrons are found in the center of an atom which is called the nucleus.
The whole is less than the sum of the parts. A proton or neutron (nucleon) will have less mass in a nucleus that outside it. That's because some of the mass of a nucleon is converted into binding energy to hold an atomic nucleus together. That's the so-called mass deficit. Oh, and before we go, a proton or neutron is called a nucleon only inside the nucleus of an atom. We don't apply that term to either one when they're outside the nucleus.
Protons and neutrons are in the nucleus, and electrons are in the cloud that surrounds it.
the nucleus is surrounded by electrons, protons and neutrons. Inside the nucleus are quarks. (for the nucleus in an atom only)
The Nucleus. Which is inside the electron clouds.
The PROTONS and NEUTRONS. Collectively they are called ' nucleons'. Electrons are in energy shells around the nucleus.
protons and neutrons
Two protons and (two) neutrons inside the nucleus of the atom. Two electrons outside the nucleus.
Positively charged protons and neutral neutrons (inside the nucleus) and negatively charged electrons revolving outside the nucleus.
Protons are found in nucleus inside an atom.
No, the nucleus is part of the atom.
Protons and neutrons are in the atomic nucleus; electrons are around nucleus.
The nucleus is the center of an atom. The protons and neutrons are inside the nucleus. The electrons are outside the nucleus.
