| Research into the atom's nucleus has uncovered a variety of subatomic particles, including quarks and gluons. |
| They all have no nucleus and survive in the highest atmosphere, the hottest volcanic vents, and everywhere in between. |
| An atomic orbital is the region around the nucleus of an atom where an electron of a particular energy is most likely to be found. |
| The protons and neutrons in the nucleus are made of elementary particles called quarks. |
| The nucleus reorganizes during this time, as sister chromosomes pair and the synaptonemal complex forms. |
| The region occupied by some atomic orbitals is spherical with the nucleus of the atom at the center of the sphere. |
