Think for a moment about an atom of the element lead (atomic number 82) inside the radio that you listen to in the morning. In which of the following places has this atom probably NOT been during the course of its existence a. a previous generation star
b. a supernova explosion
c. the Sun
d. a cloud of gas and dust which would clump to become a star and a family of planets
e. the Earth's crust

c. the Sun

Explanation:

Considering the description made in the question about the atom of a lead with atomic number 82, the place t his atom probably have NOT been during the course of its existence is the SUN

The reason is that SUN is believed to consist of ten significant elements, which are: Hydrogen, Helium, Oxygen, Carbon, Nitrogen, Silicon, Magnesium, Neon, Iron, and Sulfur.

Also, some of the properties of lead show that it won't have existed in the Sun before. For example, it is a poor transmission of heat. Also, it doesn't react with oxygen in the air and doesn't burn as well.

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.
