Explanation:

• For "This is a group of protons and neutrons in the center of all atoms", the nucleus is the central part of an atom containing protons and neutrons.
• For "Heat transfer by electromagnetic waves", radiation is the transfer of heat via electromagnetic waves.
• For "This is the period of time it takes for a radioactive sample to decay to half of its original amount", half - life is defined as the time for a radioactive substance to reduce to half its initial quantity.
• For "Atoms of the same element with varying number of neutrons", isotopes are atoms of the same element having different neutron numbers.

Answer:

• "This is a group of protons and neutrons in the center of all atoms" → Nucleus
• "Heat transfer by electromagnetic waves" → Radiation
• "This is the period of time it takes for a radioactive sample to decay to half of its original amount" → Half - Life
• "Atoms of the same element with varying number of neutrons" → Isotopes
