what are the forces that holds the nuclear componends of the atoms?

This is because there are Positive Protons in the nucleus of an atom, and Negative electrons orbiting the nucleus in shells. They balance eachother out to a certain extent and keep the atom toghether. Depending on the number of protons too electrons etc can decide how stable an atom is, and also what name it is. Hence this is when some elements are more stable than others

what are the subatomic particles and type and functions

Electrons protons and neutrons are all found inside an atom and, as such, are all subatomic particles. Protons and neutrons are found in the nucleus and electrons spin around the nucleus in orbitals. The number of protons in an atom is called its atomic num,ber and there are the same number of protons and electrons. The number of protons added to the number of neutrons is its atomic mass. The number, of protons and neutrons are normally the same. If the number of neutrons differs, however, you then have an isotope
