Formation of Elements and Neutron Star Collisions

Which elements were formed shortly after the Big Bang?

• Hydrogen, Helium, and Lithium

• Carbon, Nitrogen, and Oxygen

• Gold, Silver, and Platinum

What process was observed during the neutron star collision that explained the formation of elements heavier than Iron?

• Nuclear fusion

• Rapid neutron capture process

• Radioactive decay

• Slow neutron capture process

What did the gravitational wave detectors LIGO and Virgo detect that led to the discovery of the r-process?

• A neutron star merger

• A black hole merger

• A solar flare

• A supernova explosion

Which element's discovery confirmed the occurrence of the r-process during kilonovae?

• Platinum

• Gold

• Strontium

• Uranium

What is the slow neutron capture process (s-process) responsible for?

• Producing half of the heavy elements

• Forming light elements

• Creating black holes

• Generating gravitational waves
