Explanation:

Analyze Inorganic Chemistry study areas

Inorganic chemistry is the branch of chemistry that deals with the synthesis and behavior of inorganic and organometallic compounds. This field covers chemical substances that are not carbon-based (which are covered by organic chemistry), including metals, minerals, and organometallic compounds. Among the options provided:

• "It studies processes at the cellular-molecular level" describes biochemistry.
• "It studies motion, energy, force, time, thermodynamics of chemical systems" describes physical chemistry.
• "It studies structural properties of molecules" is a general description often associated with physical or analytical chemistry, but inorganic chemistry specifically focuses on non-organic substances, including man-made synthetic materials like catalysts, coatings, and materials. Thus, "Man made products" is the most fitting choice among the options provided for what inorganic chemistry studies.

Determine the number of protons

Using the History of Atomic Theory knowledge point, we understand how the structure of an atom is defined. The atomic number of an element is defined specifically as the number of protons found in the nucleus of every atom of that element. Therefore, to find the number of protons, we look at the atomic number of the element in the periodic table.

Determine the number of neutrons

The mass number of an atom is the sum of its protons and neutrons. Since the atomic number represents the number of protons, we can calculate the number of neutrons by subtracting the atomic number (protons) from the mass number (protons + neutrons).
