This subatomic particle, found in the nucleus alongside neutrons, carries a positive charge and determines an element's atomic number.
Difficulty: Easy- Proton
- Electron
- Quark
- Positron
This heaviest naturally occurring element, with 92 protons, slowly decays through a series of alpha and beta emissions eventually becoming stable lead.
Difficulty: Medium- Thorium
- Uranium
- Radium
- Polonium
This theoretical limiting mass, roughly 1.4 solar masses, is the maximum for a white dwarf star before electron degeneracy pressure fails and collapse begins.
Difficulty: Hard- Schwarzschild limit
- Oppenheimer-Volkoff limit
- Chandrasekhar limit
- Eddington limit
The center of an atom, containing most of its mass packed into an incredibly tiny space, is known by this term.
Difficulty: Easy- Nucleus
- Electron cloud
- Valence shell
- Ion core
When a nucleus absorbs a neutron and immediately splits, this type of fission occurs without any delay from an excited intermediate state.
Difficulty: Medium- Prompt fission
- Delayed fission
- Spontaneous fission
- Photofission
This decay mode involves direct emission of a helium-14 cluster rather than individual alpha particles, observed in some heavy actinide nuclei.
Difficulty: Hard- Proton emission
- Cluster radioactivity
- Heavy ion emission
- Nuclear fragmentation
This uncharged particle shares the atomic core with protons and helps stabilize heavy atoms by counteracting electrical repulsion.
Difficulty: Easy- Electron
- Neutron
- Photon
- Meson
George Gamow invoked this wave-mechanical phenomenon to explain how alpha particles escape nuclei despite lacking energy to surmount the Coulomb barrier.
Difficulty: Medium- Wave-particle duality
- Quantum entanglement
- Quantum tunneling
- Heisenberg uncertainty
