no.
Yes, they test that along with your physical abilities.
There is a lot! Organic-chemists, analytic- , physical-, bio-, inorganic , process-, kinetic , ect...
First, you have to volunteer for it. You'll be selected based on the need to train snipers in your unit, your physical abilities, your marksmanship abilities, and whether or not you're judged to be ready for such a course.
The physical properties of technetium were determined after the war by different chemists and physicists around the world.
An inorganic chemist, or an organometallic chemist. Othe chemists for example Organic chemists, physical chemists and biochemists are interested in aluminium chemistry or behaviour when it relates to their field. Metallurgists and materaisl scientists also study aluminium but focus on the metal itself e.g. production, physical properties etc.
to get the original elements of it
The possessive form of the plural noun chemists is chemists'.Example: The chemists' laboratories are in this building.
Periodic table help to estimate the chemical and physical properties of elements.
Chemists are primarily interested in studying physical changes, which involve a change in appearance or state of matter without a change in composition, and chemical changes, which involve a change in the chemical composition of a substance.
Physical abilities typically reach their peak in early adulthood, around the ages of 20 to 30. During this stage, individuals often experience optimal strength, speed, endurance, and overall physical performance. Factors such as genetics, training, and lifestyle can influence these peak abilities, but generally, this period is when the body is most capable of high-level physical activity. After this peak, physical abilities may gradually decline with age.
If this is a homework question, your teacher should be ashamed. The answer is probably supposed to be "analytical chemistry." However, organic chemists, inorganic chemists, physical chemists and biochemists all might do this to some extent, so really a better answer would just be "chemistry" and even that might be too narrow.
