Question

question 1 - 9
scientists who study elements and how they interact are called chemists. which of the following would a chemist most likely study?
the evidence of changes in the climate of the ancient earth
the structure and properties of elements like oxygen and iron
the formation of stars and galaxies
the behavior of microscopic organisms in a pond

Explanation:

Chemists study the structure and properties of elements. The first option is related to biology (organisms), the second to astronomy (stars, galaxies), and the fourth to geology/climatology (climate change). Only the third option about elements' structure and properties aligns with chemistry.

Answer:

The structure and properties of elements like oxygen and iron
