Chemist
A chemist studies the composition, structure, properties, and changes of matter. They explore the elements, molecules, and compounds that make up substances and how they interact with each other.
A metallurgist is a scientist who specializes in the study of metals, their properties, and how they can be used in various applications. They may work to develop new metal alloys, improve metal production processes, or study the behavior of metals under different conditions.
A chemist would study hydrogen, oxygen, and other basic substances as part of their work in the field of chemistry. Chemists focus on the composition, structure, properties, and reactions of substances at the molecular and atomic levels.
Organic Chemists spend 100% of their time studying and working with Carbon-based (Organic) Chemicals. Many Mining and Chemical Engineers do too, depending on their area of major concentration.
Ahemist is the type of scientist that studies elements, atoms, molecules .
Depending on what their studies focus on, the scientist would be one of the followingbiochemistmicrobiologistcellular biologistgeneticist
A physicist studies motion. This field of study includes understanding the properties of objects in motion, analyzing the causes of motion, and predicting the behavior of objects based on their motion.
An entomologist is a scientist that studies insects and 'bugs.' A chiropterologist is a scientist who studies bats. An ornithologist studies birds. It would depend on what small, winged creature was being studied.
