Heavy elements like Pb (lead)and U (Uranium)were generated ________.
A)by humans in nuclear reactors
B)during the big band when the universe was formed
C)by the Sun and expelled to the solar system via the solar wind
D)during collapse of a star and subsequent nuclear synthesis in a supernova

Question

Quizplus · Accepted Answer

Heavy elements like lead and uranium are created through the process of nuclear synthesis in a supernova, where a star collapses and produces heavy elements through nuclear fusion reactions. This process is also responsible for creating other heavy elements like gold and silver. Option A is incorrect as nuclear reactors create different isotopes of these elements but not heavy elements. Option B is invalid as the Big Bang only created light elements like hydrogen and helium. Option C is also incorrect because the solar wind does not produce heavy elements.
