low level waste
Explanation:
Low level wastes are nuclear wastes generated from hospitals and industries as well as the nuclear fuel cycle, and is comprised of paper, rags, tools, clothing, filters, etc., which contain small amounts of mostly short-lived radioactivity.
- Low level wastes are typically radioactive in nature and are difficult to dispose.
- They originate from radioactive processes in the hospital and nuclear reactors.
- There has been growing concerns about the safe disposal of radioactive wastes over the years.
- They are made up of materials with short lived radioactivity.

Answer:
The purpose of molecular modeling is to provide a three-dimensional image (either physical or software-based) that allows a chemist to better see the manner in which atoms and molecules can interact. These models can be used to interpret existing observations or to predict new chemical behavior.
Explanation:
It can describe shape and how they connect while forming the electrons.
